A function is a block of code that can be defined once and reused any number of times. When writing programs, it is best practice to break up complex programmatic processes into smaller units that perform specific tasks. Doing this has many advantages, some of which are:

• Improving code readability: It is much easier to read programs that have been broken down into functional units. This is because the scope of the code to be understood at any given point in time is reduced when functions are utilized. The majority of the time, a programmer needs to only write or adjust a section of a large code base. When functions are utilized, the context of the program that needs to be read to ameliorate program logic is restricted to the body ...
