Conversion code


The easiest and smallest code available to convert infix expression to postfix expression.
Can somebody give the code?

Sounds like a homework assignment.

And you didn't even google for various solutions already on the net.

No! not a homework. I have a program that converts an infix expression to a parse tree. wanted to see if it can convert a postfix expression as well, so figured, maybe if i added a small fragment to convert infix to postfix in the code,it'll all work out. But i don't seem to find any small code. All the codes i came across have taken the long route. So i was just wondering if there is a smaller version which could perform the same action.

Did you mean "convert to" rather than "convert"? In that context, "convert" would mean "convert from", which is opposite your original request.

Almost all the code needed to convert from infix to parse tree is the same as almost all the code needed to convert from infix to postfix.

If you already have code to convert infix to parse tree, it should be trivial to add code to make it convert to postfix as well or optionally instead.
