Oh im sorry, like i said b4, im new... I get what you mean now.. You mean that if i just compiled and built the executable ... it wouldnt just run on all comps and applications, right? Why is that, cause the conio library isnt included with all consoles? This is my first language... and i understand what i have learned in my college programming class, but they havent covered portability. And sorry for asking newbie questions.

Because, from what I understand, conio.h (which is a borland file, doesn't even work for me in Dev-C++) is not included with Linux. You would need to use the appropriate header file for Linux to get clrscr() compatible with Linux.

Newbie questions are just fine, as long as you put a little research into your question (or answer for that matter)

Dev-Cpp has a (somewhat raped) conio.h. Woiks fine here. Except on my Braille output device, of course. Normally, I just use the console IO from Windows for my non-portable stuff. Hell to have to write 5 lines of code to clear the screen, but what can I say?

i believe (i may be wrong) that conio.h has been deprecated. it's good to get in the habit now of writing portable code. what dawei is saying is that it may work on your computer in your development environment and all that happy shit, but may have weird results on other systems (like crashing). it's like telling someone on a rotary phone to "hit *67" to call back, it's not portable. in college even this may come back to bite you in the ass if whomever is grading your stuff is running on a non-compliant system. even worse in the professional environment.

how is one to know what is portable and what isnt? is that something you are taught, or something you just figure out with use of programs? i mean, i think its kinda ridiculous and a waste of time to make large programs that you are unsure of there running capabilities...

There is a thing called the standard library. THAT is what is portable. Sometimes you don't want/need portable. That's fine too, in that case it helps to mention what OS and system you want your code for.

Almost nothing that actually DOES anything, beyond calculate, is portable. Different systems have differing input devices and differing output devices. Shit fahr, man, keypads and keyboards aren't even the same. Look at your calculator keyboard up'side your telephone keypad. Breathe deeply and pump some actual oxygen into your braincells, sit on the corral fence for five minutes, and work 'em.
