Hi all, again...

Well I got this part of the code:

do {
printf("Valor corrente: %f\n",anarec.curval);
sleep(3);
ch = getch();
}
while (ch!='q' && ch!='Q');
exit(0);

What I want to do is when the "q" key is pressed the program just quit, but using this getch() the user must hit ENTER after pressing "q". How do I fix the program so the user just hit the "q" key to exit??

Thanks for your help.

I'm no expert, but I'm under the impression there is no great way to accomplish this.

If on a unix system you could try something like.

(Toggle Plain Text)

system("stty raw");
while (ch!='q' && ch!='Q');
system("stty -raw");

also search for curses.h
or conio.h if for DOS

With getch(), you shouldn't have to press Enter after pressing "q" - are you sure you're using it right? And don't use exit; use return.

(Toggle Plain Text)

 do {
    printf("Valor corrente: %f\n", anarec.curval);
    sleep(3);
}
while ((getch() | 0x20) != 'q');
return 0;

yo spydoor,

that worked just fine, thx a lot. The only thing is, using this raw mode my output is beeing tabed, but it works.

oh yeah.
