Create a program that calculates the factorial of a number n, entered by the user with WHILE-LOOP. The program will NOT use the MATLAB function that calculates the factorial. Use while (logic condition) Algorithm end The user enter n, and your program must calculate the value of n! Create the mechanism to warn the user if that has an error when enter a negative number to calculate the factorial. Also, set the condition so that when the number n is zero the result by definition is 1. So the factorial of zero is 1. Print the result in complete sentence that reads: The factorial of (should appear here the number entered by the user) is the result you have computed]
