sizeof获取类型大小

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

int main( void )
{
    printf("int %d/n", sizeof(int));
    printf("short %d/n", sizeof(short));
    printf("long %d/n", sizeof(long));
    printf("long long %d/n", sizeof(long long));
    printf("float %d/n", sizeof(float));
    printf("double %d/n", sizeof(double));

    return 0;
}
