Functions:- function is a block of code that executes a specific task when it is called. It combines some set of instructions into that particular block to execute the task.
In computer science, a pointer is a programming language object, whose value refers to (or "points to") another value stored elsewhere in the computer memory using its memory address. A pointer references a location in memory, and obtaining the value stored at that location is known as dereferencing the pointer.
In a function call, the types of the evaluated arguments must match the types of their corresponding parameters. If they do not match, the following conversions are performed in a manner that depends on whether a prototype is in scope for the function:
Recursion:- recursion is the process in which a function calls itself again and again to solve a specific problem.

In object-oriented programming, a class is an extensible program-code-template for creating objects, providing initial values for state (member variables) and implementations of behavior (member functions or methods).
