C++ Concepts: Improve Type Safety with C++ 20

Solution: A Custom Concept Using Concepts from the C++ STL

Explore how to build custom concepts in C++20 by using existing concepts from the standard library. This lesson helps you understand modeling requirements, simplifying concepts, and enhancing type safety in template code through practical examples and best practices.

We'll cover the following...

Solution

Let’s check the solution below:

C++
#include <iostream>
#include <concepts>
using namespace std;
template<typename T, typename Base>
concept ExerciseConcept = std::copyable<T>
  && std::constructible_from<T, int, float>
  && std::derived_from<Base, T>;
int main()
{
    //no need to write anything here
}
