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
The game continues without the decision of winner/loser till the last vacant cell on the board. Here is the snap of the `gameEnds()` function, which calls the `checkTie()` function.


bool gameEnds(char board[], char currentPlayer) {
    if (checkWin(board, currentPlayer)) {
        displayBoard(board);
        cout << "\nPlayer " << currentPlayer << " wins!\n";
        return true;
    }
    if (checkTie(board)) {
        displayBoard(board);
        cout << "\nThe game is a tie.\n";
        return true;
    }

    return false;
}

What if all the places are taken and nobody wins? This case is a tie. Let’s set up a function to check if the game ties. 

# Requirements of this module

The function `checkTie()` should perform the following tasks:
- Receive one parameter: `board`.
- Checks for a tie after each move from the start. 
- If all the places on a board are not filled, it returns `false`. 
- If all the places on a board are filled, and no one wins, it returns `true` and the game ends.

# Try it yourself

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