Description

Randomly generate numbers between 1 and 1000 for user to guess.

Demo Code

#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;

void guessGame(); // function prototype
bool isCorrect( int, int ); // function prototype

int main()//from   w ww .  j av  a  2  s .  com
{
   srand( time( 0 ) ); // seed random number generator
   guessGame();

   return 0; // indicate successful termination

} 
// guessGame generates numbers between 1 and 1000 and checks user's guess
void guessGame()
{
   int answer; 
   int guess; // user's guess
   char response; // 'y' or 'n' response to continue game

   do {
      answer = 1 + rand() % 1000;

      cout << "Can you guess my number between 1 and 1000?\n" << "Please type your first guess." << endl << "? ";
      cin >> guess;

      while ( !isCorrect( guess, answer ) ) 
         cin >> guess;      

      cout << "\nYou guessed the number!\n" << "Would you like to play again (y or n)? ";
      cin >> response;

      cout << endl;
   } while ( response == 'y' );
}

bool isCorrect( int g, int a )
{
   // guess is correct
   if ( g == a )
      return true;

   // guess is incorrect; display hint
   if ( g < a )
      cout << "Too low. Try again.\n? ";
   else
      cout << "Too high. Try again.\n? ";

   return false;
}
