                      Recap



                          A function is a block of organized 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.
