像这样：
```cpp
string a,b;
cin>>a>>b;
string x,y;
while(cin>>x>>y)
{
......
}
```

@[chenyue2](/space/show?uid=188885) 最好还是文件输入输出吧……
`EOF`绝对是这个世界上最恶心的东西

@[OvO自动机](/space/show?uid=122689) I don't think so.

@[OvO自动机](/space/show?uid=122689) 你把...!=EOF改成~...不就行了？

@[Hopjac—Programmer](/space/show?uid=168334) 个人经历表示EOF老是欺负我

这样:
```cpp
string str;
while (!cin.eof())
{
cin >> str;
if (!str.size())
break;
srcarr.push_back(std::move(str));
cin >> str;
dstarr.push_back(std::move(str));
}
```

```cpp
while(cin.good())
{
cin.clear();
\\输入
}
```
这样也可以
