remove_const Class
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
