/*
!Note
* The keyword unsigned means that the value cannot be negative number
* By default datatypes are signed, meaning they can hold negative and positive values
* You can declare short int without typing the "int" keyword (example: short myint = 2;)
* Normal int data type is considered long int, that is why there is another data type long long, to represent huge numbers
