Hi, in C# please!

Assignment 4C: Factorial! There's a nifty math concept called factorial that illustrates for loops beautifully. To find the factorial of a number, you multiply all descending numbers starting at the original number. For example, if you want to find the factorial of 6 (denoted 6!), you will multiply all descending numbers starting at 6. 6! = 6*5*4*3*2*1 = 720 We will use this concept to design our program for this part of the assignment. Write a program that asks the user to enter an integer. The program will calculate the factorial of the inputted number then return the product as an integer. The sample output is shown below. User input is in bold. Sample Output 1 Enter an integer: 5 The Factorial of 5 is: 120 Sample Output 2 Enter an integer: 10 The Factorial of 10 is: 3628800
