I meant I would print "\b \b", but I just want to give the user the option of deleting characters with backspace or delete.

So I was messing around with implementing backspace and also reading it into into an array today and think I've got it working fairly well. Correct me if I'm wrong, but getchar() turns the input into a unique integer right? Well I want to display the password that was entered just to check, but if everything has been converted into integers, how do I display it?

And I'll narrow my earlier question changing the colors into something that is answerable. Basically I want to do something along these lines:

Code:

  while ((ch = getchar()) != '\n')
   {
      if(ch == '\b')     /*Here is where I want to give the option of using delete*/
      {
         printf("\b \b");
         i--;
      }

      else
      {
         password[i] = ch;

         if((ch == '1')    /*I'm not sure if this is done correcting. I want to print a red "1" if a 1 was typed*/
         {
            printf("\033[1;3;31;49m1\033[0m");         /*Output a red '1'*/
         }

         else((ch == '2')    /*Same issue*/
         {
            printf("\033[1;3;34;49m2\033[0m");         /*Output a blue '2'*/
         }

         else((ch == '3')     /*Same issue*/
          {
             printf("\033[1;3;32;49m3\033[0m");         /*Output a green '3'*/
          }

         i++;
      }
   }

I guess this is kinda similar to my first question, this time comparing something that has been turned into an integer to an input. I commented on the lines I am referring to.

xstdcmap

XSTDCMAP(1)						      General Commands Manual						       XSTDCMAP(1)

NAME

       xstdcmap - X standard colormap utility

SYNOPSIS

       xstdcmap [-all] [-best] [-blue] [-default] [-delete map] [-display display] [-gray] [-green] [-help] [-red] [-verbose]

DESCRIPTION

       The  xstdcmap  utility  can  be	used to selectively define standard colormap properties.  It is intended to be run from a user's X startup
       script to create standard colormap definitions in order to facilitate sharing of scarce colormap resources among  clients.   Where  at  all
       possible, colormaps are created with read-only allocations.

OPTIONS

       The following options may be used with xstdcmap:

       -all    This  option  indicates that all six standard colormap properties should be defined on each screen of the display.  Not all screens
	       will support visuals under which all six standard colormap properties are meaningful.  xstdcmap will determine the best allocations
	       and visuals for the colormap properties of a screen. Any previously existing standard colormap properties will be replaced.

       -best   This option indicates that the RGB_BEST_MAP should be defined.

       -blue   This option indicates that the RGB_BLUE_MAP should be defined.

       -default
	       This option indicates that the RGB_DEFAULT_MAP should be defined.

       -delete map
	       This  option  specifies	that a specific standard colormap property, or all such properties, should be removed.	map may be one of:
	       default, best, red, green, blue, gray, or all.

       -display display
	       This option specifies the host and display to use; see X(7).

       -gray   This option indicates that the RGB_GRAY_MAP should be defined.

       -green  This option indicates that the RGB_GREEN_MAP should be defined.

       -help   This option indicates that a brief description of the command line arguments should be printed on the standard error.  This will be
	       done whenever an unhandled argument is given to xstdcmap.

       -red    This option indicates that the RGB_RED_MAP should be defined.

       -verbose
	       This option indicates that xstdcmap should print logging information as it parses its input and defines the standard colormap prop-
	       erties.

ENVIRONMENT

       DISPLAY to get default host and display number.
