C++入门--3.0复合类型

#include<iostream>#include<cstring>//cstring头文件 using namespace std; int main() { //----------------------1.0 字符数组---------------------------- //初始化 方法1 //char dog[8]={'a','b','c','d','e','f','g','h'}; //char cat[8]={'a','b','c','d','e','f','g','\0'}; ////法2初始化 //char dog_B[8]="yanggan"; //char cat_B[8]="justtes";//输入不能超过7个，第8位默认为 ‘\0’  //for(int i=0;i<8;i++) //{//cout<<dog_B[i]; //}  //----------------------2.0字符数组中 使用字符串---------------------------- const int Size =15; char name1[Size]; char name2[Size]="c++cowboy"; cout<<"hello,i am "<<name2<<"!,what is your name?"<<endl; cin>>name1; //sizeof()计算数字长度，而strlen()计算数组中字符串的长度。 cout<<"well,"<<name1<<",you name has "<<strlen(name1)<<" letter.\n";//计算字符长度 cout<<"And is stored in an array of "<<sizeof(name1)<<" bytes."<<endl;//计算数组长度 name2[3]='\0';//用 '\0'替换掉字符数组中第三个，然后输出时候读取到'\0'就停止了 cout<<"Here are the first 3 characters of my name : "<<name2<<endl; }
