Code for calculator
Hello,
I need code for a c++ calculator that is based on a stack data structure. It must be able to evaluate expressions like :
( 3 * 4) + ( 6 + 2)
3 + 4
(6 *9) / (2 * 4)
Thank you

In the 'Annotated C++ Reference' of Bjarne Stroustrup there was a calculator sample. It was 15 years ago where I enhanced it to a class based sample and add some more functions and operand handling. But the basic sample was rather complete and it should not be difficult to google for it.

BTW, is it a homework assignment? EE experts may not post full code samples for homework. So, if it is homework I only could help if you show some attempts of you to solve the problem yourself.

based on my other post you can probably see i attempted and I couldnt get it to work. thats why im paying to get some help.

Actually I wrote the starter code from scratch and on my own. Believe it or not, Im not trying to "buy" anyone over, Im trying to get help. I asked for help on the parenthesis part, and people suggested I wrote it using different methods I don't know how to write. Please don't make assumptions. Thanks for your help
Alex is right!
If this is homework then we are not allowed to post full code examples. That's EE rules, we don't make them but also we don't break them. Look at the code you already have, identify what you don't understand and ask specific questions here. You'll find EE experts will be only too willing to assist with specific problems but not one of them will post you full code -- no matter how many times you say you've tried but can't do it! If you are that stuck you'll need to refer back to your professor.

it uses infix. if you are familer with tree traversal methods, then you can try with prefix and post fix aswell
