1stly I've searched the forum and read relevant post and am still none the wiser!!! I am currently trying to learn C++, and at college we use the M$ compiler and at home I have Bloodshed and Redhat 9. A task was to use buffered and unbuffered input and output. The functions given with a brief explanation were:- _kbhit , ungetch , getch , getche , putch , and cputs to start with.

//Example of _kbhit

#include <stdio.h>
#include <conio.h>

int main()
{
cputs ("Hit any character ket when ready\n");
while (! _kbhit())
; //inifinite loop til a key pressed
cputs("The key pressed was ");
putch(getch());
putch('\n');
return 0;
}

The above works fine on bloodshed and M$ but gives numerous errors when compiling with g++, any help will be greatly aprecited!!

Thanx in advance......

OK, the answer is rather simple (once you know the answer )

The funtions _kbhit , ungetch, etc, are provided with the conio library. This is specific dos, (although may have been ported to other platforms (?)).

Under linux the common replacement in the curses/ncurses libraries

If you must use conio functions (I wouldn't) I found this on google. http://www.ibiblio.org/linsearch/lsm...onio-1.02.html

If you are learning C++, you are probably better off to use the iostream libraries.

Hi,
First thing that you should know is that C on Linux/*nix is different than C on M$. Programs written for M$ cannot be so easily ported on the Linux/*nix and vice-versa. So, header files,functions and system calls which you have used on M$ may or maynot be available on Linux/*nix(like conio.h, kbhit() etc). So, the best way which I can think of is to get hold of a good book/docs which teaches c/c++ on linux. This will be much better I suppose. Hope this helps

The best thing to do is learn the standard to then know what is portable and what is not. Then you can abstract the non portable implementation away from the 'real' code..

Marshall Cline, has a book (the real paper back one, not the online lite version) covers most of the important aspects of using the C++ standard and I recommend it to all programmers (not only C++ programmers).

C++ FAQ Second Edition



And The C++ Professional Handbook covers the standard to a technically detailed level (down to some specific compiler implementation details). And is another book I would recommend to every C++ programmer.

Cheers

When it comes to C++, the ONE book u must read is The C++ Programming Language by Bjarne Stroustrup.

Can't disagree more. That is definitely not a book to give someone who's a C++ newbie. I know, cause I've been through that purgatory.

A much better book for beginners would be C++ Primer by Stanley B. Lippman and Josée Lajoie.

That said, Stroustrup's book is a good reference material for one reason -- since Bjarne is C++, if his book says one thing and the compiler disagrees, then the compiler needs to be changed.
