# Computing the Factorial of a Number Using Three Separate Functions (Coursework Sample)

Instructions:

write a program that will compute the factorial of a number using three separate functions.
Function 1 is to get the data from the user so we call it getInput().
Function 2 is to compute the factorial of the number we call it
factorial ().
type the below program, compile,, link and generate the
executable file ‘factorial’. Then, submit both the source code and
the output in a PDF file for your Assignment-4 on Chapter-4.
Below is my version that did on my Linux server, and I
demonstrated it to you all, please feel free to make changes as you
like, test it and make sure it is working completely before you
