Learn Memory Management in C

Completed course from boot.dev.

The exercises from the course have been worked out in this repository. This is my way of obtaining the "certificate" for free. The first the 3 chapters of the course can be done interactively on the website.

/riyyi/bootdev-c/src/commit/780996458b70dcc32b9c1ce0efd4757046f1aa2d/bootdev-c.png

If you're reading this with the intention of completing the exercises yourself, you can find each exercise is in its own directory inside of the src directory. Remove all the files that each exercise mentions you should modify, as you go through them. Then recreate the files from the exercise, so you won't get spoiled.

Notes:

  • In order to verify allocations in the unit tests, please use the wrapper functions boot_malloc, boot_calloc, boot_realloc and boot_free from boot_lib.h instead of the stdlib.h allocation functions
  • In chapter 6 exercise 6, macOS malloc will almost never return a NULL pointer due to virtual memory overcommit, so you should check for size == 1024 * 1024 * 100) instead of array == NULL
  • In chapter 8 and 11, I renamed stack_t to my_stack_t due to a std naming conflict on macOS

Build instructions

Compiling and running all the tests can be done with the following commands:

$ mkdir build
$ cd build
$ cmake ..
$ make run

Output

Successful output of all the tests:

$ make run                                                                                                                                                                                     12:25PM
