remove_const Class

Makes a non const type from type.

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

T

The type to modify.

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

 

#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
