End Game

What we have

We already have almost a complete game, but after checking the winner of each round, we have to display the results at the end. This is our inventory of already created functions:

// Function to display game introduction and rules
void displayIntroductionAndRules() {
    cout << "Welcome to Rock-Paper-Scissors game!\n" << endl;
    cout << "The rules of the game are simple:" << endl;
    cout << "1. Rock beats scissors" << endl;
    cout << "2. Scissors beats paper" << endl;
    cout << "3. Paper beats rock" << endl;
}

// Function to get number of rounds
int getRound() {
    int rounds;
    cout << "How many rounds would you like to play? ";
    cin >> rounds;
    return rounds;
}

// Function to get player's choice
string getPlayerChoice() {
    string choice;
    cout << "Choose rock, paper, or scissors: ";
    cin >> choice;
    return choice;
}

// Function to generate computer's choice
string generateComputerChoice() {
    srand(time(NULL));
    int rand_num = rand() % 3;
    if (rand_num == 0) {
        return "rock";
    } else if (rand_num == 1) {
        return "paper";
    } else {
        return "scissors";
    }
}

// Function to determine the winner of the round and update scores
void determineWinner(string player_choice, string computer_choice) {
    if (player_choice == computer_choice) {
        cout << "It's a tie!" << endl;
    } else if ((player_choice == "rock" && computer_choice == "scissors") ||
               (player_choice == "scissors" && computer_choice == "paper") ||
               (player_choice == "paper" && computer_choice == "rock")) {
        cout << "You win!" << endl;
        player_score++;
    } else {
        cout << "The computer wins!" << endl;
        computer_score++;
    }
}

What now?

We can create a function to print the results when the game ends. It should print a final message and display the scores of both players. These are the steps we need to perform in this task:

• Print the final scores.
• Announce the winner.
