echo \"hello"\>hello.c后如何退出

代码:

typedef struct Score
{//成绩结点，定义在#include之后
int rank;
double time;
int guess_times;
char name[16];
char date[26];
}node, * S_pointer;

typedef struct NodeHead
{//链表头结点，定义在#include之后
int length；
S_pointer head;
S_pointer handle;
S_pointer temp;
S_pointer tail;
}list;
============
使用如下：在main()函数里
list.length=0;
list.temp=NULL;
list.handle=NULL;
list.head=NULL;
list.tail=NULL;
