Welp, Back to the drawing boards.
I'm also looking for suggestions on additional functions. so suggest some.

maybe stuff for a statistics class.

or finding what percentile a number falls into.

UPDATE:
I Noticed that my cout was getting a little big so I replaced it with an fstream so the list of of functions pops up in notepad. However whenever i compile it notepad doesn't pop up. Could someone paste this into their compiler and tell me if this works for them, and point out any bugs if any.
Thanks,
eXtensible
and to the people who suggested functions, thanks.

Why would you expect notepad to pop up? All your code does is write your Function list to a file called functions.txt. You would need to add additional code to invoke notepad but I personally don't see any advantage to it. What you might do is make your function list multi-lined or even make sub menus with like functions grouped together.

What code would I need to write to display the file?

I would strongly suggest not saving (or writing) anything to file.
1) Users will not expect a calculator application to write anything to their filesystem, this on it's own is a good reason not to do it
2) If the calculator is invoked in a different directory, it will write a new Functions.txt
3) If the calculator is invoked in a diectory where the user does not have write permissions (or is mounted read-only), it will crash
Invoking notepad from your calculator is an even worse idea.

So I'm Probably Better off Just Using a cout?

ok, So I Downloaded something called MathGL to Help me with functions using graphs. However I'm not sure how to start using it. Can anyone direct me to any tutorials for using MathGl.
Thanks,
