Initially, I was confused about when to use const vs constexpr in C++ & how this constexpr works & differ with const. So, I have studied this from different sources & here is the consolidation of it: Primitive constexpr Variables 1 2 3 int varA = 3; const int varB = 5; constexpr int varC = 7; All of the above variable having a value which is known at compile time.
