编程问题 急 ！！！

printf("\nsizeof(unsigned int)=%d",sizeof(unsigned int));
printf("\nsizeof(float)=%d",sizeof(float));
printf("\nsizeof(double)=%d",sizeof(double));
}

#include

main()
{
printf("sizeof(char)=%c",sizeof(char));
//输出字符的长度
printf("\nsizeof(int)=%d",sizeof(int));
//输出整型的长度
printf("\nsizeof(short)=%d",sizeof(short));
//输出短整型的长度
printf("\nsizeof(long)=%f",sizeof(long));
//输出长整的长度
printf("\nsizeof(unsigned int)=%c",sizeof(unsigned int));
//输出无符号整型的长度
printf("\nsizeof(float)=%f",sizeof(float));
//输出浮点型的长度
printf("\nsizeof(double)=%f",sizeof(double));
//输出双精度的长度
}

printf("sizeof(char)=%d",sizeof(char));
