remove_const class

Makes a non-const type from a type.

Syntax

template <classT> structremove_const; template <classT> usingremove_const_t = typename remove_const<T>::type;

Parameters

T

Remarks

An instance of remove_const<T> holds a modified-type that is T1 when T is of the form const T1, otherwise T.

Example

#include<type_traits> #include<iostream>intmain() { int *p = (std::remove_const_t<constint>*)0; p = p; // to quiet "unused" warning std::cout << "remove_const_t<const int> == " << typeid(*p).name() << std::endl; return (0); }

remove_const_t<const int> == int
