A while Loop - Generate a random number between 0 and 9
and let the user guess it.
Use a while loop.  Exit when user guessed right.

#include <iostream>
// <cstdlib> is needed in order to use the rand().
// For older compilers, use <stdlib.h>
#include <stdlib.h> 
using namespace std;

int main()
{
  int magic;  // magic number
  int guess;  // user's guess

  cout << "I will come up with a magic number between 0 and 9 ";
  cout << "and ask you to guess it." << endl;

  magic = rand()%10; // get a random number between 0 and 9
  
  cout << "Enter your guess: ";
  cin >> guess;

  while (guess != magic)  // as long as guess is incorrect
  {
	  if(guess > magic)
	  {
	          cout << "Too big! Guess again..." << endl;
	  }
	  else            // guess is less than magic
	  {
		  cout << "Too small! Guess again..." << endl;
	  }
	  cin >> guess;
  }
  cout << "You are RIGHT!" << endl;;
  return 0;
