数组型（二维）
#include<stdio.h>
int main()
{
int a[3][4] = {0};
printf("%d\n",sizeof(a));
printf("%d\n",sizeof(a[0][0]));
printf("%d\n",sizeof(a[0]));
printf("%d\n",sizeof(a[0]+1));
printf("%d\n",sizeof(a+1));
printf("%d\n",sizeof(&a[0]+1));
printf("%d\n",sizeof(*a));
printf("%d\n",sizeof(a[3]));
return 0;
}
（一维数组）
#include<stdio.h>
int main()
{
int a[] = {1,2,3,4};
printf("%d\n",sizeof(a));
printf("%d\n",sizeof(a+0));
printf("%d\n",sizeof(*a));
printf("%d\n",sizeof(a+1));
printf("%d\n",sizeof(a[1]));
printf("%d\n",sizeof(&a));
printf("%d\n",sizeof(&a+1));
printf("%d\n",sizeof(&a[0]));
printf("%d\n",sizeof(&a[0]+1));
return 0;
}
