#include<stdio.h>

int main(int argc, char* argv[])
{
	//有符号
	int a = 10;
	short b = 20;
	long c = 30;
	long long d = 40;
	//输出单位为占用字节数
	printf("%d", sizeof(a));//4
	printf("%d", sizeof(b));//2
	printf("%d", sizeof(c));//4
	printf("%d", sizeof(d));//8

	//无符号
	unsigned int au = 10u;
	unsigned short bu = 20u;
	unsigned long cu = 30lu;
	unsigned long long du = 40llu;

	printf("%d", sizeof(au));//4
	printf("%d", sizeof(bu));//2
	printf("%d", sizeof(cu));//4
	printf("%d", sizeof(du));//8

	return 0;
