Learn Memory Management in C

Get close to the metal: pointers, the stack, the heap, and a tiny garbage collector you build yourself.

What you'll learn in this C course

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

Great intro to C and memory management. I've always wanted to learn C and lower level programming, and this was a great way to get started.

Pretty good course, wasn't as bad/hard as I expected it to be. (coming from C++)

I had programmed C before. the garbage collector part was fine up to refcounting but after that i just wrote programs based on the instructions and did not understand mark and sweep.

Pointers are a tough challenge and you will want to give up but it really does shine when you learn how to create your garbage collectors :)

Awesome course! A must-do for anyone in the profession not already familiar with low-level memory management.

It was very good course in the beginning.Then GC part was useless for me. Yes, i got the idea but i forgot my code after 5 min. Probably that part is not for everyone.
