Keyboard Inputs

right ive got a problem!would be cool if any1 could help!
while(1)
{

/*get key press*/
gettchar(&ch);
switch(ch)

{
case '1': /*Start Engine*/
ready();
break;
case '2' : /*test lights*/
emergency_lights();
break;

case'3': /*Exit*/
exit();
break;
}


} as far as i know this should work so when i press 1,2 or 3 it will jump into certain functions. But it doesnt like gettchar when i compile.above that part of code ive got simple printf's for menu!sorry it must be stupid question but im only begginer.thanx in advance

getchar not gettchar

and i think it is ch = getchar();

while(1)
{
char ch;
/*get key press*/
ch = getchar();
switch(ch)

{
case '1': /*Start Engine*/
ready();
break;
so it should be something like this?

Looks good to me.

In the future, please put all code between [code] [/code] tags

hmm i still get nothing...it compiles but not accessing that while(1)..ive coppied menu from my old project where it works perfectly but not working here.could it be coz of the programme i use?dev c++?

it should be case 1: for numbers. No ''

thanx guys that helped.one more question?is it possible to make it work automaticly..coz at the moment i use scanf...and if i chose option 1 i have to press ENTER all the time.any ideas about that?

No standard function can achieve this I dont think. However there are some in the conio library that can do this I believe.

What you are referring to is called unbuffered input. Do a google search for it and you should get some good results.

As valaris said, there is no standard way to achieve this. The standard io functions typically line buffer console input, which is why you have to hit the ENTER key to signify the end of a line.

great stuff guys!it all works now.gonna look up for unbuffred input now.bad thing is that dev c++ doesnt support many libraries :( maybe anybody knows any other good simply programms to use?

Good post on it:

Dev C++ is an IDE... it has nothing to do with supporting libraries. By default I believe it ships with the MinGW compiler, which you can make work with MANY libraries.

hmm i tried to add
#include <ncurses.h> and some other,after compiling it said no such a file or directory.
anyway great help guys:)

Did you download the ncurses library? It doesn't come included with the MinGW compiler...

If you're on windows I'd suggest getting the pdcurses library, if ncurses is what you're interested in.

Because I believe it's wcurses on windows.

~nm apparently this is an implementation of curses for python.

i never used dev c++ so i dont know how to download libraries for that lol..will have to have a look:)

First off, I would suggest dropping this notion that you are obtaining libraries for Dev C++. Dev C++ is an IDE (integrated development environment). The whole point of an IDE is to be the nice pretty interface that sits on top of a compiler.

The compiler that you are using is most likely the MinGW compiler. You will need to obtain libraries compatible with the MinGW compiler, and then when you are compiling a project that uses those libraries, you must tell the compiler where the libraries are and where the necessary include files are. Usually the IDE will provide you a nice graphical way to specify this (probably in the project settings).

So, lets say you download the PDCurses library. You will recieve some header files, and some DLL's (or .lib / .a files). Lets say you put your header files in C:\pdcurses\include\ and the DLL's / .libs / .a files in C:\pdcurses\lib\ . (This naming convention is pretty common).

You now need to look in your project settings and add the C:\pdcurses\include\ directory to the project include path. Likewise, you'll need to add C:\pdcurses\lib\ to the library path. You then need to tell the compiler that you want to link the pdcurses library (and it will be able to find out where it is because you added it to the library path).

I can't tell you specifically how to do this in Dev C++, but if you were compiling on the commandline you would type: gcc -I "C:\pdcurses\include" main.c -L "C:\pdcurses\lib" -lcurses, or something similar.

where n how can i download libraries for dev c ++?
