#include<stdio.h>
int main(void)
{
    printf("Type int has a size of %zd bytes.\n",sizeof(int));
    printf("Type char has a %zd bytes.\n",sizeof(char));
    printf("Type long has a size of %zd bytes.\n",sizeof(long));
    printf("Type long has a size of long %zd bytes.\n",sizeof(long long));
    printf("Type double has a size of %zd bytes.\n",sizeof(double));
    printf("Type long double has a size of %zd bytes.\n",sizeof(long double));
   
    return 0;
}

输出的数据  %zd没有转换成数值  
比如第一个显示：
   Type int has a size of zd bytes.
