// MARK: - VARIABLES

/* 
    Variables are data stored that can have their value change whenever we want it and 
    constant are value that can not be changed.

    The advantage of using var in declaring a variable and let in declaring a constant is that 
    it help xcode to remind us of the constant we have set and whenever we try to change it, 
    it will not xcode will not compile our code and it help to save memory space that is optimization of memory.
