Function Overloading in C++ with example code

Function Overloading 

Function overloading allows you to use the same function name for more than one definition in the same scope.

Function overloading has rules

first, it should have the same function name.

second, the number of arguments or the types should be different.

 

Example code

Result

When function 'func(4)' is called in main, function 'func(int a)' executed because it coincides with the type and the number of argument. And the same goes for func(int a, int b).
