User Input

What we have

We have set up taking the number of rounds from the user and the game’s introduction. 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;
}

In this task, we have to ask for user input to select one of the three options.

What now?

We can create a function that takes user input and returns it. We can follow these steps to complete this task:

• Create a variable to store the user’s choice.
• Take the input from the user.
• Return the variable.
