    colours

    hi every1
    i wnated to know if it is possible to change text colour being outputed on a unix compiler (g++). I have searched the FAQ but it seems that most of the stuff on there was concerned with windows / dos programming.
    thanks alot for ur time

    Hello,

    Are you interested in changing the color of the output of g++, or are you intending to have your programs display colored text?

    What you need is ncurses. Check out the man pages for ncurses and curs_color. I think you will find them most useful.

    int main(int argc, char *argv[])
    {
    
     initscr();
        if(has_colors() == FALSE)
        {
           endwin();
            printf("You terminal does not support color\n");
            exit(1);
        }
        start_color();  /* Start color */
        init_pair(1, COLOR_BLUE, COLOR_YELLOW);
    
        attron(COLOR_PAIR(1));
        print_in_middle(stdscr, LINES / 2, 0, 0, "Viola !!! In color ...");
        attroff(COLOR_PAIR(1));
        sleep(10);
        endwin();
    }
    
    void print_in_middle(WINDOW *win, int starty, int startx, int width, char *string)
    {
    
       int length, x, y;
        float temp;
         if(win == NULL)
            win = stdscr;
        getyx(win, y, x);
        if(startx != 0)
            x = startx;
        if(starty != 0)
            y = starty;
        if(width == 0)
            width = 80;     length = strlen(string);
        temp = (width - length)/ 2;
        x = startx + (int)temp;
        mvwprintw(win, y, x, "%s", string);
