Makes non const/volatile type from type.

Syntax

template <class T>  
struct remove_cv;  
 
template <class T>  
using remove_cv_t = typename remove_cv<T>::type;

Parameters

T
The type to modify.

Remarks

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

Example

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

remove_cv_t<const volatile int> == int
