Ok I'm using Microsoft Visual c++ express edition for this programming book by Jonathan S. Harbour. Now this code below I type dit all in exactly now here is the error I get and I don't know how to fix it:

Thanks in advance .

I think you missed a 5.

blade55555

What?  ARe you being serouse or sarcastic?

Theodoryk

I'm being silly, guess I'm in one of those moods. Pay me no heed, good luck with the code.

blade55555

Yea thanks .

".maintest.c(6) : fatal error C1083: Cannot open include file: 'windows.h': No such file or directory"

The "(6)" means the error occured in line six of your code. The path to the file windows.h is not defined in your compiler. Which probably means the paths to the next two files are not defined either.

How do you do that? Hell if I know. Start the compiler, press F1, and start reading.

Dude. How are you this far into your program or book and dont' understand what you're doing? You can't just copy and paste code and expect to learn how it works. You actualy have to do it.

And.... you have a problem with your windows.h. How you fix it... I dont' know. But that's where your problem is.

If you don't know what a #include does then you need to go back to chapter 1.

I don't think he understands what he's typing. He's just typing in what htey tell him. If he can't figure out how to fix something like that and realize it's a problem with an external source, then he really doesn't understand what he's doing.

Will I'm not that far.  I'm only on like chapter 3 or 2 one of those.  And I didn't copy and paste the code I typed it out.

But you don't understand what you're typing. So it's the same thing.

We're all born ignorant mate.

Typing in programs and getting them to work is the best way to learn.
