Question

In this activity you will create a game call Guess That Number! The program has an unlimited number of rounds. In each round the program selects a random number that the user has to guess.

In Round 1 the user has to guess a number less than 5 within 5 tries. If the correct number is not guessed in 5 tries than the game is over. If the correct number is guessed than the user moves onto the next round where he/she has to guess a number less than 10 within 5 tries. In each subsequent round the range of numbers is doubled (5, 10, 20, 40, etc.).

In order to program this game you will need to use if-else statements, loops and random number generation using the cmath and ctime libraries.

// do comment if any problem arises

//code

#include <iostream>

#include <ctime>

#include <random>

using namespace std;

int main()

{

    srand(time(0));

    //0 to 5 in first round

    int max = 5;

    //initialize round to round number 1

    int round = 1;

    cout << "\tWelcome to Guess The Number\n\n";

    while (1)

    {

        cout << "\nRound " << round << endl;

        //for each round greater than 1 multiply max by 2

        if (round > 1)

            max *= 2;

        // initialize tries to 5

        int tries = 5;

        // compute correct guess

        int user_guess, Correct_guess = rand() % max;

        // give 5 tries

        while (tries--)

        {

            //read user guess

            cout << "\nEnter your guess: ";

            cin >> user_guess;

            // if user guesses correctly

            if (user_guess == Correct_guess)

            {

                cout << "You won round " << round << endl;

                round++;

                break;

            }

            else

                cout << "Incorrect guess! try again.\n";

        }

        // user is out of tries

        if (tries < 0)

        {

            cout << "You lose Correct guess is: " << Correct_guess;

            break;

        }

    }

}

Output:

Welcome to Guess The Number Round 1 Enter your guess: 5 Incorrect guess! try again. Enter your guess: Incorrect guess! try again. Enter your guess: 5 Incorrect guess! try again. Enter your guess: 5 Incorrect guess! try again. Enter your guess: 5 Incorrect guess! try again. You lose Correct guess is: 1
