Question

In c++ I want to make number matching game.

Conditions are these

:

1. Excellent! You guessed the number!

Would you like to play again (y or n)?

2. Too low. Try again.

3. Too high. Try again.

// Randomly generate numbers between 1 and 1000 for user to guess.
#include <iostream>
#include <cstdlib>
#include <ctime>
using namespace std;
void guessGame(); // function prototype
int isCorrect(int, int); // function prototype
int main()
{
   srand(time(0)); // seed random number generator
   guessGame();
} // end main
// guessGame generates numbers between 1 and 1000 and checks user's guess
void guessGame()
{
   int answer = 0; // randomly generated number
   int guess = 0; // user's guess
   char response = 'y'; // 'y' or 'n' response to continue game
                       // loop until user types 'n' to quit game
   do
   {
       // generate random number between 1 and 1000
       // 1 is shift, 1000 is scaling factor
       answer = // 1) your codes
               // prompt for guess
           cout << "I have a number between 1 and 1000. "
           << "Can you guess my number? "
           << "Please type your first guess." << endl << "?";
       cin >> guess;
       // check the guess and compare with answer.loop until correct number
       while (// 2) your codes)
           cin >> guess;
       // prompt for another game
       cout << " Excellent! You guessed the number! "
           << "Would you like to play again (y or n)? ";
       cin >> response;
       cout << endl;
   } while (// 3) your codes);
} // end function guessGame
// isCorrect returns true if g equals a
// if g does not equal a, displays hint
int isCorrect(int g, int a)
{
   // guess is correct
   //4) your codes. Check and return 1
   // guess is incorrect; display hint. Too low. Try again or Too high. Try again.
   //5) your codes. Check and return 0
} // end function isCorrect

Explanation / Answer

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

void guessGame();
bool isCorrect(int, int);

int main()
{
   srand(time(0));
   guessGame();
}

void guessGame()
{
   int answer;
   int guess;
   char response;

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

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

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

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

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

bool isCorrect(int g, int a)
{
   if (g == a)
       return true;
   if (g < a)
       cout << "Too low. Try again. ? ";
   else
       cout << "Too high. Try again. ? ";

   return false;
}
