1、通过指针修改数组元素的值

ps:int a[10] = {10}; 数组名a == &a[0]    a+1 == &a[0]+1 跨过得是数组元素类型的长度，&a是对整个数组取地址，&a+1是跨过整个数组的长度

#include "stdio.h"
#include <stdlib.h>

int main()
{
	int a[10] = { 0 };
	int* p = a;
	for (int i = 0; i < sizeof(a) / sizeof(a[0]);i++) {
        //a[i] = i;
		*(p+i) = i;
	}
	for (int i = 0; i < sizeof(a) / sizeof(a[0]);i++) {
		printf("%d=%d\n",i,a[i]);
	}
//数组{0,1,2,3,4,5,6,7,8,9}
	
	system("pause");
	return 0;
}
