C++ Example Project

This is a simple C++ project that can be built both on Windows and in a Docker container.

Building on Windows

1. Make sure you have CMake and a C++ compiler (like MSVC or MinGW) installed
2. Open a terminal in the project directory
3. Create and enter the build directory:

   mkdir build
   cd build
   

4. Generate build files and build the project:

   cmake ..
   cmake --build .
   

5. Run the executable:

   .\Debug\cpp_example.exe
   

Building with Docker

The project uses a multi-stage Dockerfile which:

1. First stage (builder) - Compiles the code with all necessary build tools
2. Second stage (runtime) - Contains only the compiled executable, resulting in a smaller, more secure final image

To build and run:

1. Make sure you have Docker installed
2. Open a terminal in the project directory
3. Build the Docker image:

   docker build -t cpp-example .
   

4. Run the container:

   docker run cpp-example
   

The multi-stage build approach ensures the final container image is minimal, containing only what's needed to run the application, without build tools or source code.

Project Structure

• src/main.cpp: Main source file containing the example code
• CMakeLists.txt: CMake configuration file for building the project
• Dockerfile: Docker configuration for containerized building and running
• .gitignore: Specifies which files Git should ignore
