Increment & Decrement

/**
You can increase a numeric variable's value by 1 using the increment operator: ++
*/

    number++;

/**
You can decrease a numeric value by using the decrement operator: --
*/

    number--;

/**
These are "post" increment and decrement.

1. The value stored in nunber is modified
2. The old value is returned

If we were to do:
*/

    int number = 5;
    int otherNumber = number++;

/**
otherNumber would contain the value 5, number would contain the value 6.
The pre-increment and pre-decrement value return the new number:
*/

    int number = 5;
    int otherNumber = ++number;
    // now both variables will contain 6.
