Info

The C Programming Language Heimo Gaicher, born in 1969, has been a passionate tinkerer, electronics enthusiast, and programmer since a young age. While working, he completed the industrial electronics master's school and later the Higher Technical Federal Institute of Electronics and Technical Informatics (BULME) in Graz. He has worked extensively in hardware and software development for LED lighting, testing environments, all-wheeldrive systems, laboratory measuring devices, and sensor technology. Preface This book is aimed at programming beginners who want to learn the universal programming language C. Since learning a programming language is not easy for beginners, this book has been created step-by-step with many examples. A general and lengthy introduction has been deliberately avoided, as the relevant examples are precisely documented in the programming code, leading to a better understanding. The book is not a comprehensive reference, but a step-by-step guide for the learner. Work through the book carefully from the beginning and try to solve the program examples independently or expand them according to your own ideas and needs. After all, the best way to learn a programming language is by programming. This book has been written with great care. If there are still errors, I welcome corresponding feedback. Comments and critiques are always welcome at c4programmers@gmail.com. Have fun experimenting! © 2023 Heimo Gaicher
