查看linux下各数据类型的大小

代码如下：

#include<stdio.h>
int main()
{
	printf("int:%d bytes\n",sizeof(int));
	printf("char:%d bytes\n",sizeof(char));
	printf("short:%d bytes\n",sizeof(short));
	printf("long:%d bytes\n",sizeof(long));
	printf("unsigned int:%d bytes\n",sizeof(unsigned int));
	printf("float:%d bytes\n",sizeof(float));
	printf("double:%d bytes\n",sizeof(double));

}

结果：

int:4 bytes
char:1 bytes
short:2 bytes
long:4 bytes
unsigned int:4 bytes
float:4 bytes
double:8 bytes
