expressionevaluator

This was the final project in my Programming Foundations 2 class.

to use it, compile all of the .cpp and .h files and run. enter a string of expressions separated by semicolons ex) 2+5;9*9/6;

then for actions, the options are

1. < for postfix

2. for prefix

3. = to evaluate
4. f to print out fully parethesized version

you can also use varaibles in the input. when evaluated, it will use the data from the varaibles ex) a+b;a=9;b=-4;
