The number N factorial, denoted by N!, is defined to be the product of the first N positive integers: N! = 1 × 2 × ... × N (For example, 5! = 1 × 2 × 3 × 4 × 5 = 120. and 7! = 1 × 2 × 3 × 4 × 5 × 6 × 7 = 5,040) Find N!, where N is a positive integer input by the user. (Hint: initialize a Product to 1 and use a loop to multiply that Product by successive integers.)
