Description

In this self-contained 11 hour course, we will be coding an e-mailserver in C, from scratch. We will not be using any external libraries or dependencies and almost no functions from the standard C library; we will be coding Everything ourselves.

In this course you will greatly improve your C programming skills and you will learn how to write a few pretty advanced functions. But most of this course is at the same intermediate level as almost all my courses and videos.

You will improve your skills in network programming/sockets, in pointers, advanced structures and you will learn how to code advanced functions.


-Why learn C from dr Jonas Birch and not from the other 10 top Udemy instructors?

Experience in the C language. When dr Birch was 18 years old and had been coding C for five years, he was traveling all over Europe, invited to different coding and security conferences, giving lectures about C and security. Since then he has coded C almost every day - for an additional 20 years!

Experience in teaching. Dr Birch has been teaching the C language (live) almost full time the last six years, helping hundreds and hundreds of students learn the mother of all languages - in Linux.

Very soothening voice. Dr Birch has a very dark, relaxing voice which is very easy to listen to (a really underestimated feature).
