```string```不能用```scanf/printf```吧？

@[Inf_Voltage](/user/119261) 啊？我是第一次用，不清楚。我看网上有说加个`.c_str()`就可以用`printf`。

这我就不清楚了/kk

@[Inf_Voltage](/user/119261) 那string应该用双引号还是单引号？
by JimmyFlower @ 2020-11-02 18:10:29
双引号吧

@[JimmyFlower](/user/124676) `.c_str()`就是把`string`转为 `char[]`，这样就可以`printf`了。
`""`是字符串`char[]/string`，`''`是字符`char`

字符和字符串都可以转化为string类型吧
没关系，不CE就行
