                    Recap



                         A function is a block of organised and reusable code used to perform a particular task.
                        Built-in functions are predefined functions provided by C++.
                        C++ allows you to create your own functions which are known as user-defined functions.
                        The parameters passed at the time of declaring a function are called formal parameters.
                        There are two methods to call a function: call by value and call by reference.
                        The scope of a variable means how different parts of the program can access that variable.
