Clone the Repository

git clone https://github.com/todorx/VS-Code-Projects.git
cd VS-Code-Projects

🔨 Building the Project

Using CMake (Recommended)

# Create build directory
mkdir build
cd build

# Configure and build
cmake ..
make

# Or use the preset (if available)
cmake --preset default
cmake --build --preset default

Using VS Code with CMake Tools

2. Install the "CMake Tools" extension
3. Select your preferred compiler kit
4. Click "Build" in the status bar

🚀 Running Exercises

After building, you can run individual exercises:

# Run all exercises
./VS-Code-Projects

# Or compile and run a specific OOP exercise
cd "OOP Exercises/Exercise-5"
g++ -std=c++11 exercise.cpp -o exercise5
./exercise5

# Or compile and run a specific structured exercise
cd structured-programming-exercises/Exercise-5
g++ -std=c++11 5.cpp -o exercise5
./exercise5
