This repository holds the solution of a pixel management fictional scenario that was part of a coding challenge. This code and its specification doesn’t match with the way pixels are managed in real life.
Use this project as a reference for:
- C project structure.
- C public headers includes and their linking.
- 3rd party library usage in C.
- Documentation.
- C language practice.
Also contains code related to:
- Pointer management.
- Bitwise operations.
- Quick sort algorithm.
- C unit testing using Unity framework.

✅ The pixel solution code is complete and tested.
-
⚠️ The Unit test framework usage needs to be improved. Right now there is a Makefile target for each test file. -
⚠️ TheMakefileneeds to be improved.
To test the project run:
make all-
Do not set the random seed every time a random number is generated. If several calls are made immediately one after the other, the random number will result in the same value always (giving you a not so random behavior).
-
Remember to free the memory you are not using when testing using loops.
-
Be careful when subtracting unsigned ints for comparison. If the numbers are too big they may overflow the sign bit of the result leading to unwanted behaviors.
