    Default Infix to Prefix

    Good day programmers. i dont know where to start but may i ask help for me to create a program that converts infix expression to prefix expression. i got the idea that i can use stack implementation for the infix-prefix converter to work. my only problem is i dont know how to implement a stack into a code that i can use for converting infix to prefix notation. I need some ideas and algorithms that can help me in my coding.

    im not a good programmer that's why i joined this forums because i think by interacting with fellow programmers, i can become good and enhance my skills by sharing ideas, opinions and algorithms with other programmers. i hope that this forums will help me grow as a programmer even little by little.... i would greatly appreciate your ideas if any... I will also try to code it then i hope that i can ask for permission for the members to check and analyze my code. this infix-prefix converter i think is a very hard program. but i hope that i can do it with the help of my fellow programmers here in this forum. thanks....

    The Shunting Yard algorithm will help you get from infix to postfix notation. From there, it shouldn't be too hard to convert to pre-fix.

    Here's a link to a simple java calculator that parses infix to post-fix (scroll down to the last post).
