 	   /* rand functions works by using an algorithm to come up with a "random" number, this number will not change because it uses 	the same algorithm everytime, to over come this we use a seed number to provide different inputs into this algorithm.
   	 To define a range of numbers for rand to find a random number in we use %, % divides the number by a number we provide and 	then gives back to us the remainder. This will provide us with a number between 0 and or given number because the remainder of 	the division cannot be larger then the given number. We then modify this range by adding a number to it to give us our starting 	point. eg. range 50-55 = %5 + 50 */
