You have to use the ncurses library. Here is a dumb example:

Code: Select all

#include <curses.h>

int main() {
    int code;
    
    initscr();
    while (1) {
        code=getch();
        printf("Entered: %c\n\r",code);
    }
}

You have to link this code with the -lncurses switch.
See the manual page of ncurses for more info.

i tried it but the function initscr(); cleared all what was on the terminal , and after the program finished i couldn't write any thing on the terminal . so i have to close it and open it again ..

well try this:

Code: Select all

#include <ncurses.h>

int main() {
  int c;
  initscr();
  raw();
  c = getch();
  printw("You have pressed: %c",c);
  getch(); //second time just to freez screen
  endwin();
  return 0;
}

and take a look at this:

Or better yet, forget ncurses and all, just use getchar. It is a drop-in replacement to getch() , provided by all standard C++ compilers, including gcc.
