抄写作业

#include<stdio.h>
int main()
{
struct Student
{
long int num;
char name[20];
char sex;
char addr[20];
 }
 a={10101,"lilin",'M',"123 Bei Jing Road"};
 printf("num=%d\n,name=%s\n,sex=%c\n,addr=%s\n",a.num,a.name,a.sex,a.addr);
 return 0;
}

运行结果

num=10101 ,name=lilin ,sex=M ,addr=123 Bei Jing Road

这次作业很多,写的有的是上课练习的,还比较轻松,有的却不是很好,我想大概是上学期留下的尾巴吧!我会狠抓基本功,争取做好每一次程序的
