如何比较字符串 [英] How to compare strings

问题描述

我想比较一个字符串，但实际上没有将其中一个定义为字符串，像这样，

I wanted to compare a string without actually defining one of them as a string, something like this,

if (string == 'add')

我必须声明'add'作为字符串或者是可能以类似的方式进行比较？

Do I have to declare 'add' as a string or is it possible to compare in a similar way?

推荐答案

：string类实现比较运算符，因此您可以使用 == ，如下所示：

In C++ the std::string class implements the comparison operators, so you can perform the comparison using == just as you would expect:

if (string == "add") { ... }

正确使用操作符重载是一个优秀的C ++特性。

When used properly, operator overloading is an excellent C++ feature.
