Functors are often used in functional programming to represent operations.
函数对象在函数式编程中常用于表示操作。
In C++, functors are classes that overload the function call operator.

Functors can be used to encapsulate state and behavior together.
函数对象可以将状态和行为封装在一起。
They are particularly useful in algorithms that require custom behavior.
