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.
