Tic-Tac-Toe

A simple Tic-Tac-Toe game written in C++ with unit tests using Google Test.

Prerequisites

• CMake (version 3.14 or higher)
• A C++ compiler supporting C++14 or higher.
• Internet connection (to fetch Google Test automatically via CMake).

Building the Project

Generic Build (All Platforms)

1. Create a build directory:

   mkdir build
   cd build

2. Generate build files:

   cmake ..

3. Build the project:

   cmake --build .

Windows

Using Visual Studio (MSVC)

1. Open "Developer Command Prompt for VS".
2. Navigate to the project root.
3. Run:

   mkdir build
   cd build
   cmake ..
   cmake --build . --config Release

   The executable will be in build/Release/tic_tac_toe.exe.

Using MinGW/GCC

1. Open your terminal (e.g., PowerShell or CMD).
2. Run:

   mkdir build
   cd build
   cmake -G "MinGW Makefiles" ..
   cmake --build .

macOS (Clang)

1. Open Terminal.
2. Run:

   mkdir build
   cd build
   cmake ..
   make

Linux (GCC)

1. Open Terminal.
2. Run:

   mkdir build
   cd build
   cmake ..
   make

Running the Game

After building, run the executable:

• Windows: build\tic_tac_toe.exe (or build\Release\tic_tac_toe.exe)
• macOS/Linux: ./tic_tac_toe (inside the build directory)

Running Tests

To run the unit tests:

1. Navigate to the build directory.
2. Run the test executable:
   • Windows: build\tic_tac_toe_tests.exe (or build\Release\tic_tac_toe_tests.exe)
   • macOS/Linux: ./tic_tac_toe_tests
3. Alternatively, use CTest:

   ctest --output-on-failure

Controls

The game uses a keyboard-based grid:

• q w e
• a s d
• z x c

Each key corresponds to a position on the 3x3 board.
