Learn Memory Management in C

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

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

Reealllyyy ought to have better explanations of pointers, didn't really feel like the course writers wanted you to learn pointers, it felt like they just wanted you to spam salmon to boots and make him teach you.

i am an egyptian who already learnt C in the first 2 semesters college, i want to tell you that what i learnt in college is considered nothing compared to this course, the best part about this course (and the whole platform) is that you write tons of code, and that's makes you really understand the concept

Great intro to the syntax of C and the nitty gritty of memory management. Doesn't go too deep into the C language itself, so it definitely is primarily about how you might go about managing memory.
