This course builds a classic Rock Paper Scissors game in C++ using a modular programming method for a beginner-level coder

After learning the basics of C++, it’s a great idea to complete at least one hands-on project where you can build something from scratch using C++. This course offers the opportunity to build a basic but classic Rock Paper Scissors game, command-line style.

You’ll begin the course by looking at the end product and then building the game step-by-step, adding one tiny feature in each lesson. This way, you’ll add one or two helper functions to the codebase and then test them individually in the main controller function. Because of this modular approach, you’ll finish coding the game efficiently and professionally.

By the end of the course, you’ll have one complete hands-on project in C++ added to your profile. That’s a great start!

Mini Course: Build Rock Paper Scissors with C++

# What we have

We have set up a function to print the introduction of the game. This is our inventory of already created functions:

```C++
// 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;
}
```


The next step is to ask the user about the number of rounds. This specifies how many times our game will run. 

# What now?

We need to create a function that asks users to input the total number of rounds they want to play and store it in a variable. These are the steps we need to perform in this task:

- Prompt the user.
- Take the input and store it in a variable.
- Return the variable.
