list-style: decimal-leading-zero outside none;"><span class="sh_cbracket" style="color: rgb(255, 0, 128); font-weight: bold;">}</span></li></ol>

上述代码中，以下代码：

<ol class="snippet-num" style="margin: 1em 0px 1em 1em; padding-left: 3em;"><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">    int array<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">[</span><span class="sh_number" style="color: rgb(128, 0, 128); font-weight: bold;">10</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">];</span></li><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">    <span class="sh_keyword" style="color: rgb(187, 121, 119); font-weight: bold;">for</span> <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">(</span>int i <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">=</span> <span class="sh_number" style="color: rgb(128, 0, 128); font-weight: bold;">0</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">;</span> i <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;"><</span> <span class="sh_number" style="color: rgb(128, 0, 128); font-weight: bold;">10</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">;</span> i<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">++)</span></li><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">        <span class="sh_function" style="color: rgb(0, 68, 102);">scanf</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">(</span><span class="sh_string" style="color: rgb(166, 133, 0);">"%d"</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">,</span> <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">&</span>array<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">[</span>i<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">]);</span></li></ol>

定义一个整型数组array，包含10个元素。并使用循环对元素赋值的方式完成对数组array的初始化。

上述代码中，以下代码：

<ol class="snippet-num" style="margin: 1em 0px 1em 1em; padding-left: 3em;"><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">    int num<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">;</span></li><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">    <span class="sh_function" style="color: rgb(0, 68, 102);">printf</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">(</span><span class="sh_string" style="color: rgb(166, 133, 0);">"请输入要删除的元素："</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">);</span></li><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">    <span class="sh_function" style="color: rgb(0, 68, 102);">scanf</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">(</span><span class="sh_string" style="color: rgb(166, 133, 0);">"%d"</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">,</span> <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">&</span>num<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">);</span></li></ol>

首先，定义一个整型变量num，用于存储输入的一个要删除的元素。

然后，使用函数printf提示输入的一个要删除的元素。

最后，使用函数scanf输入的要删除的元素到变量num中。

上述代码中，以下代码：

<ol class="snippet-num" style="margin: 1em 0px 1em 1em; padding-left: 3em;"><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">    int i<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">;</span></li><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">    <span class="sh_keyword" style="color: rgb(187, 121, 119); font-weight: bold;">for</span> <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">(</span>i <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">=</span> <span class="sh_number" style="color: rgb(128, 0, 128); font-weight: bold;">0</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">;</span> i <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;"><</span> <span class="sh_number" style="color: rgb(128, 0, 128); font-weight: bold;">10</span> <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">;</span> i<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">++)</span></li><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">        <span class="sh_keyword" style="color: rgb(187, 121, 119); font-weight: bold;">if</span> <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">(</span>array<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">[</span>i<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">]</span> <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">==</span> num<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">)</span></li><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">            <span class="sh_keyword" style="color: rgb(187, 121, 119); font-weight: bold;">break</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">;</span></li></ol>

设置一个循环，逐个元素array[i]与输入的要删除的元素num对比，找到要删除的元素在数组中的位置后退出循环。

上述代码中，以下代码：

<ol class="snippet-num" style="margin: 1em 0px 1em 1em; padding-left: 3em;"><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">    <span class="sh_keyword" style="color: rgb(187, 121, 119); font-weight: bold;">for</span> <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">(;</span> i <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;"><</span> <span class="sh_number" style="color: rgb(128, 0, 128); font-weight: bold;">9</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">;</span> i<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">++)</span></li><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">        array<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">[</span>i<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">]</span> <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">=</span> array<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">[</span>i <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">+</span> <span class="sh_number" style="color: rgb(128, 0, 128); font-weight: bold;">1</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">];</span></li></ol>

将找到的要删除元素的位置的下一个元素赋值到其中，实现删除的功能。设置循环，依次赋值，实现将后续元素顶上来的功能。

上述代码中，以下代码：

<ol class="snippet-num" style="margin: 1em 0px 1em 1em; padding-left: 3em;"><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">    <span class="sh_keyword" style="color: rgb(187, 121, 119); font-weight: bold;">for</span> <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">(</span>i <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">=</span> <span class="sh_number" style="color: rgb(128, 0, 128); font-weight: bold;">0</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">;</span> i <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;"><</span> <span class="sh_number" style="color: rgb(128, 0, 128); font-weight: bold;">9</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">;</span> i<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">++)</span></li><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">        <span class="sh_function" style="color: rgb(0, 68, 102);">printf</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">(</span><span class="sh_string" style="color: rgb(166, 133, 0);">"%d "</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">,</span> array<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">[</span>i<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">]);</span></li><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">    <span class="sh_function" style="color: rgb(0, 68, 102);">printf</span> <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">(</span><span class="sh_string" style="color: rgb(166, 133, 0);">"</span><span class="sh_specialchar" style="color: rgb(255, 0, 255); font-weight: bold;">\n</span><span class="sh_string" style="color: rgb(166, 133, 0);">"</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">);</span></li></ol>

设置一个循环，逐个打印数组中剩余的元素，验证删除效果。

使用循环对元素赋值的方式完成对数组array的初始化。数组的长度是使用数组所占的字节数sizeof（array）除以数组第一个元素所占的字节数sizeof（array[0]）得到的。

上述代码中，以下代码：

<ol class="snippet-num" style="margin: 1em 0px 1em 1em; padding-left: 3em;"><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">    <span class="sh_keyword" style="color: rgb(187, 121, 119); font-weight: bold;">for</span> <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">(</span>int i <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">=</span> <span class="sh_number" style="color: rgb(128, 0, 128); font-weight: bold;">0</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">;</span> i <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;"><</span> <span class="sh_function" style="color: rgb(0, 68, 102);">sizeof</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">(</span>array<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">)</span><span class="sh_normal"> </span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">/</span> <span class="sh_function" style="color: rgb(0, 68, 102);">sizeof</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">(</span>array<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">[</span><span class="sh_number" style="color: rgb(128, 0, 128); font-weight: bold;">0</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">]);</span> i<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">++)</span></li><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">        <span class="sh_function" style="color: rgb(0, 68, 102);">printf</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">(</span><span class="sh_string" style="color: rgb(166, 133, 0);">"%d "</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">,</span> array<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">[</span>i<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">]);</span></li><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">    <span class="sh_function" style="color: rgb(0, 68, 102);">printf</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">(</span><span class="sh_string" style="color: rgb(166, 133, 0);">"</span><span class="sh_specialchar" style="color: rgb(255, 0, 255); font-weight: bold;">\n</span><span class="sh_string" style="color: rgb(166, 133, 0);">"</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">);</span></li></ol>

首先，定义一个整型变量n，用于存储输入的数组长度。

然后，使用函数printf提示输入数组长度。

最后，使用函数scanf输入一个数组长度到变量n中。

上述代码中，以下代码：

<ol class="snippet-num" style="margin: 1em 0px 1em 1em; padding-left: 3em;"><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">    int array<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">[</span>n<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">];</span></li></ol>

<ol class="snippet-num" style="margin: 1em 0px 1em 1em; padding-left: 3em;"><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">    int n<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">;</span></li><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">    <span class="sh_function" style="color: rgb(0, 68, 102);">printf</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">(</span><span class="sh_string" style="color: rgb(166, 133, 0);">"请输入班级学生人数："</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">);</span></li><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">    <span class="sh_function" style="color: rgb(0, 68, 102);">scanf</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">(</span><span class="sh_string" style="color: rgb(166, 133, 0);">"%d"</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">,</span> <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">&</span>n<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">);</span></li></ol>

首先，定义一个整型变量n，用于存储输入的学生人数。

然后，使用函数printf提示输入学生人数。

最后，使用函数scanf输入一个学生人数到变量n中。

上述代码中，以下代码：

<ol class="snippet-num" style="margin: 1em 0px 1em 1em; padding-left: 3em;"><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">    int score<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">[</span>n<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">];</span></li></ol>

定义一个整型数组，数组的长度由整型变量n通过函数scanf动态输入决定。

上述代码中，以下代码：

<ol class="snippet-num" style="margin: 1em 0px 1em 1em; padding-left: 3em;"><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">    <span class="sh_keyword" style="color: rgb(187, 121, 119); font-weight: bold;">for</span> <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">(</span>int i <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">=</span> <span class="sh_number" style="color: rgb(128, 0, 128); font-weight: bold;">0</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">;</span> i <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;"><</span> n<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">;</span> i<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">++)</span></li><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">    <span class="sh_cbracket" style="color: rgb(255, 0, 128); font-weight: bold;">{</span></li><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">        <span class="sh_function" style="color: rgb(0, 68, 102);">printf</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">(</span><span class="sh_string" style="color: rgb(166, 133, 0);">"第%d个成绩："</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">,</span> i <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">+</span> <span class="sh_number" style="color: rgb(128, 0, 128); font-weight: bold;">1</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">);</span></li><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">        <span class="sh_function" style="color: rgb(0, 68, 102);">scanf</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">(</span><span class="sh_string" style="color: rgb(166, 133, 0);">"%d"</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">,</span> <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">&</span>score<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">[</span>i<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">]);</span></li><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">    <span class="sh_cbracket" style="color: rgb(255, 0, 128); font-weight: bold;">}</span></li></ol>

设置循环，逐个输入每个学生的成绩。

上述代码中，以下代码：

<ol class="snippet-num" style="margin: 1em 0px 1em 1em; padding-left: 3em;"><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">    int sum <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">=</span> <span class="sh_number" style="color: rgb(128, 0, 128); font-weight: bold;">0</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">;</span></li></ol>

定义整型变量sum，并初始化为0，用于存储班级学生总成绩。

上述代码中，以下代码：

<ol class="snippet-num" style="margin: 1em 0px 1em 1em; padding-left: 3em;"><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">    <span class="sh_keyword" style="color: rgb(187, 121, 119); font-weight: bold;">for</span> <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">(</span>int i <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">=</span> <span class="sh_number" style="color: rgb(128, 0, 128); font-weight: bold;">0</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">;</span> i <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;"><</span> n<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">;</span> i<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">++)</span></li><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">        sum <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">+=</span> score<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">[</span>i<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">];</span></li></ol>

设置循环，对每个学生的成绩进行累加，计算总成绩。

上述代码中，以下代码：

<ol class="snippet-num" style="margin: 1em 0px 1em 1em; padding-left: 3em;"><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">    <span class="sh_function" style="color: rgb(0, 68, 102);">printf</span> <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">(</span><span class="sh_string" style="color: rgb(166, 133, 0);">"总分：%d</span><span class="sh_specialchar" style="color: rgb(255, 0, 255); font-weight: bold;">\n</span><span class="sh_string" style="color: rgb(166, 133, 0);">"</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">,</span> sum<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">);</span></li><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">    <span class="sh_function" style="color: rgb(0, 68, 102);">printf</span> <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">(</span><span class="sh_string" style="color: rgb(166, 133, 0);">"平均分：%f</span><span class="sh_specialchar" style="color: rgb(255, 0, 255); font-weight: bold;">\n</span><span class="sh_string" style="color: rgb(166, 133, 0);">"</span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">,</span> <span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">(</span>float<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">)</span><span class="sh_normal">sum </span><span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">/</span> n<span class="sh_symbol" style="color: rgb(255, 0, 128); font-weight: bold;">);</span></li></ol>

使用函数printf输出班级学生总成绩和平均分。

5 二维数组的使用(续2)

5.1 问题

实现随机发牌(不带大王和小王)。

程序负责发一副标准纸牌，每张标准纸牌都在一个花色(梅花C、方块D、红桃H或黑桃S)和一个等级(2、3、4、5、6、7、8、9、T、J、Q、K、A) 。程序需要用户输入手里应该握有几张牌。

5.2 步骤

实现此案例需要按照如下步骤进行。

步骤一：定义数组。

数组suit，用于保存扑克牌的花色S、H、D、C。

数组rank，用于保存扑克牌的13张牌A、2、3、4、5、6、7、8、9、T、J、Q、K。

代码如下：

<ol class="snippet-num" style="margin: 1em 0px 1em 1em; padding-left: 3em;"><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">#include <span class="sh_symbol" style="color: rgb(255, 0, 128);

font-weight: bold;">}</span></li></ol>

步骤二：从控制台输入你要的张数。

需要定义一个变量count，用于保存输入的张数。

代码如下：

<ol class="snippet-num" style="margin: 1em 0px 1em 1em; padding-left: 3em;"><li style="padding-left: 1.5em; list-style: decimal-leading-zero outside none;">#include <span class="sh_symbol" style="color: rgb(255, 0, 128);
