我建议你改成
```cpp
scanf("%d-%d",&a,&b);
```
因为你根本就没有进行 s 的读入操作

@[Lijunzhuo](/user/734720) 但是我记得sscanf是能用的啊

我看看，稍等 @[Wangcanyuan](/user/1062722)

我知道了 @Wangcanyuan，你的s是string类型，应该是char*类型(char s[])

我的编译结果：
```
无法将参数“1”的“std:：string{又名std:：basic_string<char>}”转换为“const char*”，转换为“int sscanf（const char*，const char*…）”
```

@[Lijunzhuo](/user/734720) 问题又来了，他没有输入啊，直接就输出z了！
