remove_const Class

2018-01-02

The latest version of this topic can be found at remove_const Class.

Makes a non const type from type.

Syntax

template <class T>  
struct remove_const;

template <class T>  
using remove_const_t = typename remove_const<T>::type;

Parameters

T
The type to modify.

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>   
  
int main()   
    {   
    int *p = (std::remove_const_t<const int>*)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
