Methods & Return Types

Functions or Methods are a set of instructions bundled together to achieve a specific outcome. Functions are a good alternative to having repeating blocks of code in a program. Functions also increase the reusability of code. Values can be passed to a function using variables – we call these parameters or arguments. Functions can also return values
