Hi guys and girls

I've got another problem... I've coded the solution for this question but it's not working and i can't figure out why. Can you guys help me? Thanks if you can...

*****************************************************************
A factorial number is a number multiplied by every factor between 1 and the number, inclusive. For instance, 3 factorial is 3 * 2 * 1, which is equal to 6. Mathematically, the factorial function is denoted using an exclamation mark (!).

A negative factorial number is undefined. Your task is as follows. Design a C++ program that prompts the user to enter a positive integer number. Use a for loop to calculate the factorial value of that number. If the user enters a negative number, display a message indicating that the program calculates only factorials of positive numbers. Otherwise, display the result of the calculation.

You must define at least one function called:

factorial(x)

where this function will return an integer as the result of the computation of x!. Hence, calling this function with factorial(3) will return 6.
