Скачать или смотреть Function Overloading | Functions with Same Name | C++

Function overloading is a feature in C++ where two or more functions can have the same name but different parameters. It means the data type and sequence of the parameters, for example the parameters list of a function myfuncn(int x, float y) is (int, float) which is different from the function myfuncn(float x, int y) parameter list (float, int).
Function overloading can be considered as an example of polymorphism feature in C++.
The easiest way to remember this rule is that the parameters should qualify any one or more of the following conditions, they should have different type, number or sequence of parameters.
Instead of defining two functions that should do the same thing, it is better to overload one.
