Exploring the Standard Type Traits: Part 2

Understand type transformation using metafunctions in C++ template metaprogramming.

We'll cover the following...

Type Traits for Certain Transformations

Name	Description
`add_cv` `add_const` `add_volatile`	Add the `const`, `volatile`, or both specifiers to a type.
`remove_cv` `remove_const` `remove_volatile`	Remove the `const`, `volatile`, or both specifiers from a type.
`add_value_reference` `add_rvalue_reference`	Add an Ivalue or value reference to a type.
`remove_reference`	Removes a reference (either value or rvalue) from a type.
`remove_cvref`	Removes the `const` and `volatile` specifiers as well as value or value references from a type. It combines the `remove_cv` and `remove_reference` traits.
`add_pointer`	Adds a pointer to a type.
`remove_pointer`	Removes a pointer from a type.
`make_signed` `make_unsigned`	Make an integral type (except for `bool`) or an enumeration type either signed or unsigned. The supported integral types are `short`, `int`, `long`, `long long`, `char`, `whar_t`, `char8_t`, `char16_t`, and `char32_t`.
`remove_extent` `remove_all_extents`	Remove one or all extents from an array type.
