How can I evaluate sums eg:


(10+5)*(1+2)

and get it to equal 45, is there a libary/function/class/thing to do this?

Where do you unzip it?

Is this for a class that you are taking? If so, perhaps the point of the exercise is for you to develop a stack container, then translate the expression into postfix notation, and from here, compute the result.

It isn't for a class, I'm just thinking of doing a calculator and wondering if there was an easy way to do the sums.

You've been linked to an implementation complete with source. What more do you need?

You have to signup for codeproject to download files.

The src of an example use is on the site...

I have downloaded it, do I just unzip it in my project directory?

Sorry, but I think there are reasonable assumptions to be made about free code - one of those assumptions is "can look at code and work out how best to use it in your project"

I have NO idea what your project folder looks like, nor how best to lay out a helper library in whatever IDE you're using. No idea at all. This is the kind of thing you're meant to be able to do yourself if you're writing code - at least, I dunno, look inside the Zip file and determine the shape of what's inside
