Predefined Concepts
Explore predefined concepts in C++ templates such as Integral and Equal, using variable and function concepts to enhance generic programming. Understand syntactic sugar, concept definitions, and how concepts enforce type constraints for safer and clearer code.
We'll cover the following...
Before moving on to predefined concepts, let’s get to know about Syntactic Sugar.
