Hi Richmond, Some years ago, Alex Tweedly recommended this book to learn C. I bought this for US$ 30 on Amazon: https://www.amazon.com/Illustrating-C-Ansi-Iso-Version/dp/0521468213 More recently, another developer recommended this 2015 book: https://www.amazon.com/Programming-Absolute-Beginners-Guide-3rd/dp/0789751984/ Al
