    Calculator v3.0.0

    This is version 3 of my calculator program. Featuring more formulas, which can be found at: http://mathworld.wolfram.com
    *NOTE: #23 & #24 are untested. If someone knows if the answer given is right or not, please tell me*
    Any and all feedback is welcome.
    And no, it's still not graphical.

    It's still not useful.

    There's no way to calculate 23 * 5 + 45 without manually remembering the number. Add a memory feature.

    The program enters an infinite loop if characters are typed in.

    To evaluate a string such as 23*5+45 you can convert it to postfix and evaluate that. Its a good exercise in the use of stacks
    Couldn't think of anything interesting, cool or funny - sorry.

    Well, I've got a new addition added. The program now has a memory function. It's still a little buggy on an aspect, so I'm not uploading it until I get it fixed. Here's what it does:
    1] It saves the last number entered into a global double

    2] Saves the value to a file

    3] Gives the user the menu choice again.

    Probably, not the best, but it works. Thanks Sang-drax for telling me that.

    You might try looking at these plot3d programs,open source and very well written,found them very helpful.Have looked at some of the other files but those stood out as well done.
