Sorry I am sending so many messages, but I have a piece of code that is annoying me beyond words to describe.

I have been working on making things like the number of players, number of slots, and beans per slot adjustable, then I am going to move on to enforce game rules.

But the code that is getting in my way is the fact that I cannot make the array's values change.

Your Goal

Your goal is pretty simply stated:

Demonstrate the extent of what you've learned in the class by creating the most flexible, feature-rich, readable implementation of the game of Nim that you can.

On the D- side

It's possible to make a basic working game of Nim (where the players have to enforce some of the rules) in 20 lines of C code, using only a few of the tools we've introduced (variable declaration, arithmetic, assignment, printf, scanf, and while loops). In fact, just such code is provided to you as a sample you may start from (see below)

If the documentation and code style (formatting, comments, magic numbers, naming) aren't horrible, that'd be enough for a bare minimum passing grade.

#Context

Read about Egyptian Multiplication on Wikipedia

Compile and run a C version to watch it in action

Look at the PEP/8 version to see how to find parity

#Task 1: Make a PEP/8 function that conforms to this external interface

	Welcome to Nim


	How many piles would you like to use? The number is usually 3, but this version allows up to ten.3
	How many players will be in this game? No more than ten can play.Cannot be less than zero.
