# 6-5 字符串比较
函数fun的功能是比较两个字符串,如果s1=s2则返回值0如果s1>s2则返回值1如果s1<s2则返回-1
### 函数接口定义:
```c++
int fun(char a[],char b[]);
```
其中`a`、`b`是用户传入的参数。 函数比较两个字符串,如果`a`=`b`则返回值0如果`a`>`b`则返回值1如果`a`<`b`,则返回-1。
### 裁判测试程序样例:
```c++
#include "stdio.h"
#include "string.h"
int fun(char a[],char b[]);
int main()
{int t;
char s1[40],s2[40];
gets(s1); gets(s2);
t=fun(s1,s2);
printf("%d\n",t);
return 0;
}
/* 请在这里填写答案 */
```
### 输入样例:
```in
asd
fg
```
### 输出样例:
```out
-1
```
