🚀 Getting Started

Prerequisites

• C++ compiler (GCC 7+, Clang 6+, or MSVC 2017+)
• Text editor or IDE (VS Code, CLion, Dev-C++, etc.)
• Basic understanding of programming concepts

Compilation Instructions

Each example can be compiled individually:

# For single file compilation
g++ -std=c++17 -Wall -Wextra filename.cpp -o output

# For files with multiple dependencies
g++ -std=c++17 -Wall -Wextra *.cpp -o output

# With debugging information
g++ -std=c++17 -Wall -Wextra -g filename.cpp -o output

Running Examples

# Navigate to specific topic folder
cd basics/variables_datatypes/

# Compile and run
g++ -std=c++17 variables_example.cpp -o variables_example
./variables_example

📖 How to Use This Repository

1. Browse by Topic: Navigate to folders based on the concept you want to learn
2. Read the Code: Each file contains detailed comments explaining the concepts
3. Compile and Run: Test the examples to see them in action
4. Modify and Experiment: Change the code to better understand the concepts
5. Practice: Use the examples as reference for your own projects

📝 Code Examples

Each topic folder contains:

• README.md: Explanation of the concept
• example.cpp: Basic implementation
• advanced_example.cpp: More complex usage
• exercises.cpp: Practice problems (when applicable)

🛠️ Compilation Standards

All code examples are written to be compatible with:

• C++11 (minimum standard)
• C++14, C++17, C++20 features marked clearly
• Cross-platform compatibility (Windows, Linux, macOS)
