Type-Traits Overview

Understand how C++ type-traits enable compile-time type analysis, optimize algorithm selection based on types, and perform type transformations and checks. Learn the roles of primary and composed type categories, type comparisons, and transformations in improving code correctness and performance.

We'll cover the following...

Type-Traits Library

Type-traits enable type checks, type comparisons, and type modifications at compile-time.

Below are some applications of template metaprogramming:

  • Programming at compile-time
  • Programming with types and values
  • Compiler translates the templates and transforms it in C++ source code

We need to add a type_traits library in the header to enable all the functions present in the library.

#include <type_traits>

Type-Traits: Goals

If you look carefully, you’ll see that type-traits have a significant optimization potential. In the first step, type-traits help to analyze the code at compile-time and ...
