解决不用sizeof求出int大小的方法
摘要:代码如下所示:复制代码代码如下:#includeintmain(intargc,char*argv[]){inta[2];unsignedi...
代码如下所示:
复制代码 代码如下:
#include <stdio.h>
int main(int argc, char *argv[])
{
int a[2];
unsigned int add1 = &a[0];
unsigned int add2 = &a[1];
printf("The address of a[0] is %u/n",add1);
printf("The address of a[1] is %u/n",add2);
printf("The size of int is %u/n", add2 - add1);
}
输出结果是:
The address of a[0] is 3218821936
The address of a[1] is 3218821940
The size of int is 4
