I was tryin to make a very simple calculator. Just for addition and subtarction, nothing fancy. But have no knowledge on how to make a sotware.

I googled and learnt that you need to write some kind of codes. No problem, I will try to google that too. But where do I write the code? Is it wordpad or notepad or do I need some special program?

Thanks in advance.

Is this for fun or a class project? Windows comes with a built in calculator...

There are scores of ways to do this. If you are looking for a simple windows like calculator, you can try coding in Java, if you know the language. Visual Basic is real neat, and I love the interface and ease of use. You can also use Visual C++ to do C coding, but it's much harder, and requires a lot more knowledge of Windows programming.

With all this, the best solution I have seen for you is Java, with it's wonderful GUI support.

If all else fails, just try using C code (you can use Notepad or any pad you want, not the ladies version though :) !) You will need to download the C compiler to do this. Google for TC compiler for example.

Here is an example (out of millions) to build a simple calculator in Java.

thx sangitsaukin for prompt reply. i will have to download tc compiler it seems coz all i know about java is there was a big earthquake there about few weeks back.

no shiv, its not for class project. i just want to expand my knowledge of compuyter beyond word and excel

--Here is the code for plus and minus.
--You can run it on sql server query analyzer

CREATE FUNCTION Calculator
(@var1 INT,
@var2 INT,
@op VARCHAR(1))
RETURNS INT
AS
BEGIN
DECLARE
@result INT
IF (@op = '+')
SELECT @result = @var1 + @var2
IF (@op = '-')
SELECT @result = @var1 - @var2
RETURN (@result)
END

SELECT dbo.Calculator(10,2,'-')

DREAMER:
if you are just starting with programming, and your knowledge is limited to word,excel etc., then the best way to start is not with programming a calculator software but just a simple one.

I suggest using VBA (already available in your Excel and word).

ask for details if you r interested.
