MASTERING SWIFT - Functions
Hi there ...
This is the twelfth chapter of Mastering Swift Tutorial series. In this chapter we are gonna learn function. Function is a block of code that performs a specific task. We can give a name to that block of code and use it in our project. Function provides reusability. That means we can use the same function in our code more than once. We can also define some parameters in other words arguments in the function. And we can use these parameters in our function. Function also allows us to return back a value to where it is called.
