Cut and paste the following code into an empty program.

int Factorial$($int Num$)\{//$ Terminating condition if $($Num $<=1)$ return$(1)$; $//$ Recursive case else return$($ Num $*$ Factorial$($Num$-1))$; $\}$

In the main program, add code to prompt the user for a value of "Num" and call this function to calculate "Factorial$($Num$)".$ Test your program with a variety of values of "Num". What is the largest factorial value you can calculate? What happens if you enter a negative value? Cut and paste some sample program output below.

What is a Factorial? How to Calculate Factorials with Examples

A factorial is a mathematical operation that you write like this: n$!.$ It represents the multiplication of all numbers between $1$ and n$.$ So if you were to have $3!,$ for example, you'd compute $3$ x $2$ x $1($which $=6).$ Let's see how it works with some more
