Hi Axel! 😃 Thank you so much for taking the time to read my article and leaving such a kind comment. I'm glad to hear that you found it helpful and enjoyed the introduction to C. As for the main.h header file, I'll definitely make sure to cover that in a future post. Stay tuned! If you have any other questions or topics you'd like me to cover, feel free to let me know. Thanks again for your support and encouragement!
