A Pair of Simple C++ Animations

A simple 1-D animation simulating a pub crawler trying to avoid CPD and make it safely to the Bar. If you minimize your output window to a single line, you can get the animation affect.

// Animation of drunk pub crawler 
#include<iostream>
#include<cmath>
#include<cstdlib>
#include<ctime>
using namespace std;
int main (){
  srand(time(0));
  const int SIZE=60;
  cout << "Enter your character symbol to begin \n ";
  char x; cin>> x;
  int position = SIZE /2;

  while (true) {
    cout << "|CPD|" ;
    for (int i=0; i<SIZE;i++) {
      if (i == position) 
        cout << x;
      else cout << " ";}
    cout << "|Bar|" << endl;

    int move= rand()%3 - 1;
    position = position + move; 
    if (position <1) {cout << "SORRY: YOU GO TO JAIL" <<endl; break;}
    if (position >SIZE-1) {cout << "Cheers: you made it to Cheers" << endl; break;}
    for(int sleep=0; sleep< 5000000 ; ++ sleep);
  }   
  cout << "   Game Over - type q quit";
  cin >> x;
  return 0; 

}//end main
