 A *function object*, or *functor*, is any type that implements `operator()`. This operator is referred to as the *call operator* or sometimes the *application operator*. The C++ Standard Library uses function objects primarily as sorting criteria for containers and in algorithms.
 
-Function objects provide two main advantages over a straight function call. The first is that a function object can contain state. The second is that a function object is a type and therefore can be used as a template parameter.

-The last argument to `remove_if` is a function object that returns a boolean value (a *predicate*). If the result of the function object is **`true`**, then the element is removed from the container being accessed by the iterators `first` and `last`. You can use any of the function objects declared in the [`<functional>`](../standard-library/functional.md) header for the argument `pred` or you can create your own.
