Compile-time checking of function existence in C++ 11, 17 and 20

1. 1Check if a function exists in a class using SFINAE (Substitution Failure Is Not An Error) in C++11
2. 2Use constexpr functions in C++17 to perform compile-time checks
3. 3Apply Concepts in C++20 to constrain template parameters and ensure function existence
4. 4Test and validate the existence of functions using static_assert
5. 5Configure and optimize code logic based on function existence using if constexpr

Software engineers and developers working with C++ can benefit from this technique to improve code quality and reduce runtime errors
