请写一个程序，用来输出你电脑上各个数据类型的长度。
参考答案：
#include <stdio.h>
int main(int argc,char **argv)
{
printf("char: %d\n", sizeof(char));
printf("unsigned char: %d\n", sizeof(unsigned char));
printf("short: %d\n", sizeof(short));
printf("unsigned short: %d\n", sizeof(unsigned short));
printf("int: %d\n", sizeof(int));
printf("unsigned int: %d\n", sizeof(unsigned int));
printf("long: %d\n", sizeof(long));
printf("unsigned long: %d\n", sizeof(unsigned long));
printf("long long: %d\n", sizeof(long long));
printf("unsigned long long: %d\n", sizeof(unsigned long long));
return 0;
}
