Thread: Erase what you just printed in a while loop

Code:

#include <iostream>
#include <conio.h>

int main()
{
  int x = 0; //Horizontil coordinates
  int y = 0; //Vertical coordinates
  int whereToGo; 
  while (whereToGo != 27)
  {
  for (int i = 0; i < y; i++)
  {
  cout << "\n";
  }
  for (int i = 0; i < x; i++)
  {
  cout << " ";
  }
  cout << "*";
  whereToGo = getch();
  if(whereToGo == 80)//if press down arrow then make y = 1 + y
  {
  y++;
  }
  if(whereToGo == 72)//if press up arrow then make y = y - 1
  {
  y--;
  }
  if(whereToGo == 77)//if press right arrow then make x = 1 + x
  {
  x++;
  }
  if(whereToGo == 75)//if press left arrow then make x = x - 1
  {
  x--;
  }
  }
  return 0;
}

I am making a simple program that makes it look like the little * is moving. but after whereToGo = getch() i need it to erase what it print before that... do you understand what i mean?... please help
