Learn Memory Management in C

Learn how to manually manage memory in C and build a garbage collector from scratch.

What will you learn?

Memory management is something that every programmer needs to deal with and understand at some point. If you're used to working with languages and tools that handle it for you, this course will teach you how all that works under the hood. You'll even build your own garbage collectors from scratch. This course will teach you the C basics you need for the course, but it's not a course about C, it's about memory.

Chapter List

1
C Basics
Introduction to the basics of the C programming language
2
Structs
Understand how C structs work and how they're laid out in memory
3
Pointers
You thought pointers were hard? Wrong. Let's figure them out together.
4
Enums
Learn how to use enums (enumerations) in C to create a set of named constants.
5
Unions
Unions in C are not the same as they are in TypeScript. Let's grok C unions.
6
Stack and Heap
Understand the difference between allocating memory on the stack and the heap
7
Advanced Pointers
Let's practice some more advanced pointer concepts - like pointers to pointers
8
Stack Data Structure
Build a stack in C using structs and pointers and understand where the memory is allocated
9
Objects
Implement your own object system for later use in your garbage collection algorithms
10
Refcounting GC
Implement a simple reference counting garbage collector from scratch in C
11
Mark and Sweep GC
Implement a basic mark and sweep garbage collector and understand its tradeoffs with refcounting

this is an awesome course, I had learned C and memory management before but this was a good refresher and went deeper.

Fun and engaging way to learn about memory management! I'm surprised by how garbage collectors actually worked under the hood

Starts easy, but at the end it becomes really challanging. Sometimes I did not really know what I actually did and just went on with the assignment. Overall it is an amazing sneak peek into the complex machinery of a garbage collected language like python. I really enjoyed the journey into the world of C.

Intersting course; great change of scene from the ususal programming style. Must know knowledge for anyone looking to be that bit more as a programer. You dont learn this with javascript.
