c/c++(疑5) 说了那么多，来试一试最简单的

</pre><h1>以最简单的一维数组说明：</h1><pre class="cpp" name="code">#include <stdio.h>#include <stdlib.h>void main(){int arr[] = {1,3,5};//一般数组赋值int arr1[3];for (int i =0; i < 3; i++){arr1[i] = arr[i];//这个没什么好说的了printf("arr1[i] =%d\n", arr1[i]);}//指针数组赋值int *arr2[3];//指针数组，说明了，指针指向一个数组，和arr类型匹配了for (int i =0; i < 3; i++){arr2[i] = &arr[i];printf("arr2[i] =%d", *(arr2[i]));printf("*(arr2 + i) = %d\n", **(arr2 + i));}const int *p;int const *p1;int (*p3)[3];//数组指针p3 = &arr;//数组整体大小空间for (int i =0; i<3; i++){printf("------p3 =%d\n", **(p3++));//越界}//printf("&arr =%d------", &arr);//printf("arr =%d\n", arr);p = arr;for (int i =0; i<3; i++){printf("%d\n",*p++);}//int *const p2;//指针本身值不能改变，未初始化报错int *const p2 = arr;//printf("%d\n",*p2);/*for (int i=0; i < 3; i++){printf("%d\n",*p2++);//p2 不可改变，所以懂了撒}*/system("pause");

数组和 指针几种常用形式

#include <stdlib.h>#include <stdio.h>void main(){int arr[] = {1,2,3,4,5,6};int *ptr;ptr = arr;for (int i =0; i < 6; i++){printf("*(ptr + i) = %d,*(arr+i) = %d\n", *(ptr+i),*(arr + i));}for (int i =0; i < 6; i++){printf("*ptr++ = %d,,arr[i] = %d\n", *ptr++,arr[i]);}system("pause");}

指针修改数组

#include <stdlib.h>#include <stdio.h>void main(){int arr[] = {1,2,3,4,5,6};int *ptr;ptr = arr;//指针去修改数组值for (int i =0; i < 6; i++){*(ptr+i) = 15;//最重要还是这句ptr = arr; 就是说你可以使用ptr 替换arrprintf("*ptr++ = %d\n", *ptr+i);}system("pause");}
