Hello there, i think there's something wrong with the code..
i entered the infix expression


the output of your code in postfix expression is this:

ABC*DE^F/G*-H*+ <- is this really correct?..

think there's a problem with the '^' and '/'..
im confused now..
which operator should be executed first?..

ABC*DEF^/G*-H*+ <- isn't it supposed to be like this?..

^ is not supported in the above code.

Hi! I found this article really helpful and I'd like to extend my thanks to you. However, I was wondering if I would like to input numbers more than 9 (i.e 10, 23, 15), how could I possibly accomplish that? I would really be grateful on your response.
