##Calculator Challenge

###Summary:

You must create a calculator that can follow the order of operations. Try to pack as many features as you can into the program while still making it easy to use/navigate. Get creative, design it however you wish! Your entry will be judged, so please make it as neat as possible!

Which language? :slight_smile:

What about languages that don’t compile or compile at runtime?

10

I’ll update the main post.

11

Programmed in batch:

start calc.exe

Results may be platform dependent.

Also I really don’t get your requirements. May only see one line at a time? Run twice? You mean like for debugging? And if it doesn’t work you have to what, start over and just rewrite your code?

Considering his only response was to like your post…

Ouch.

13

One line may only be visible at a time.

Start completely over.

14

I would have preferred the “challenge” to be a time limit.

I guarantee no one here is going to abide by the 1-visible-line rule. Or the compile rule, for that matter.

It runs on the honor system. :wink:

16

shrugs I don’t think I’m honorable enough to not just lie about how many times I tested the project. :stuck_out_tongue: Let alone how many lines I was looking at at once.

17

Well then you are disqualifed xD

Might add some rules for the calc…

* and / has priority over + and -
solve braces () first then the rest
calculate from left to right

If you don’t specify that this might happen:
6/2(1+2) = 6 / (2*(1+2)) = ( 6 / 2 ) * (1+2)
9 = 1 = 9

It should follow the PEMDAS rules.

Parentheses
Exponents (You dont have to include these)
Multiplication
Division
Addition
Subtraction

So Parentheses is first, and Subtraction is last.
