quick question

[Hologram]

This problem has been stairing me in the face for a little bit and I know it's probably just an easy fix. But I'm stumped for right now. I'm working in a linux enviroment and I wanna display text to the screen. That is no prob. But after words I would like to reset the location of the active character to the start of the text I just wrote and re-write over it. How abouts do I relocate the active character (or cursor) to the start of the text I just displayed?

Thanx,

You probably have to create a window before you can do that. I could be wrong though. I don't know much about Linux.

I would try an ascii code for the carriage return. This should return the cursor to the beginning of the line instead of scrolling to the next.

ascii code is 13 dec
D hex
015 oct

I could be wrong, but if you know the length of the input line, try using a counter when sentence is input, maybe then you could use,

for(i = len; i < 1; i--) printf("\b");

this I think would clear previous sentence input and put cursor back at the beginning. Just a shot in the dark though.

Well the simple way is to use ANSI escape sequences for controlling the cursor position

For more features, consider ncurses

heres a small counter program i wrote that might give you an idea as to how to do what you want:

#include <stdio.h>

#define WAIT 9000000 //wait time will vary for different systems

int main(void)
{
   int x, i, n = 10, back = 1, count;

   for(i = 0; i <= 200; ++i)
   {
      for(x = 0; x < back; ++x)
         printf("\b \b");

	 if(i % n == 0)
         {	
	    ++back;
	    n *= 10;
         }

        printf("%i", i);
        
	//so you have time to view the number
	for(count = 0; count < WAIT; ++count);
   }
   return 0;
}

hope this helps.
