Operator overloading is another feature I could have used but didn’t. Whenever the compiler sees such an operator, it simply replaces it with the appropriate function call. So in the code listing that follows, the last two lines are equivalent and the performance penalty is easily understood...

Function OverloadingUsed to facilitate compile-time polymorphism by allowing creation of more than one function with the same name but with different parameters.C++20#include <iostream> class human { public: int height; float weight; human(int h, int w) { height = h; weight = w; } }; ...
public enum class E { e }; void f(System::String ^s) { s += E::e; // in VS2019 C2845: 'System::String ^': pointer arithmetic not allowed on this type. } To avoid the error in this example, use the += operator with the ToString() method: s += E::e.ToString();.Initia...
