What is function overloading in C++?

Answer:

With the C++ language, you can overload functions and operators. A function Overloading is a common way of implementing polymorphism. Overloading is the practice of supplying more than one definition for a given function name in the same scope. A user can implement function overloading by defining two or more functions in a class sharing the same name. C++ can distinguish the methods with different method signatures (types and number of arguments in the argument list).

Note: You cannot overload function declarations that differ only by return type
