This course will teach beginner-level coders to build the classic game Tic-Tac-Toe in C++ using a modular programming method.

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 the basic but classic Tic-Tac-Toe 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.

Tic-Tac-Toe with C++

# What we have
If the game does not end, then we should prepare for the next round. In Tic-Tac-Toe, we need to switch the players before starting the next round.

# Requirements of this module

In this task, we want to change the value of `currentPlayer` variable. We first check its current value then modify it accordingly. We can return the new value on the basis of the current value of this variable. However, we have received the parameter as reference so that the changed value can be made visible in the caller function (`play()`) without returning through explicit use of the return statement. The function `switchPlayer()` should perform the following tasks:
- Receive `currentPlayer` as a reference parameter.
- Check the current value of the parameter.
- Change the value of the parameter.

# Try it yourself

All the functions are already defined. You just have to implement the given function and execute the code.
