# Assignment – Simple Memory Manager

With this assignment you shall implement a simple memory manager in C.

## Assignment Objective

Implementation of a memory management system as a replacement for malloc and free.

## Assignment

Technical details regarding the implementation of the memory manager are stated in file `mem_man.c`.
- Implement all functions declared in `mem_man.h`.
- Implement unit tests, at least those that are declared in `test_mem_man.h`
- Add additional unit tests as needed.

## Working Instructions

1. Implement all missing but required functions of all files mentioned below empty to make the
   application compilable and runnable. Most unit tests will be red.  
   **--COMMIT--**
1. 'test_mem_man.c': Implement all declared unit tests. Run those tests, they shall be red, because non of the tested functions is implemented yet.  
    **--COMMIT--**
1. 'mem_man.c': Implement all functions defined by this file.
  - Obey comments in header files and source code. 
  - Run the unit tests frequently and fix failures.
  - Make all unit tests green.  
    **--COMMIT--**
1. 'test_mem_man.c': Extend the unit tests with additional test cases.  
   **--COMMIT--**
1. 'mem_man_app.c': Implement the main application according to the requirements state in the source file of the application.  
   **--COMMIT--**
1. Run and stabilize the application. 

## Notes

- `general.h` contains macros for finding the minimum, maximum, and absolute value 
- make clean test: This new make target for clearing the console, building, and running unit test is available.
- Sometimes changes are not properly detected by incremental builds. If something very strange 
   happens during compilation, try to run `make clean` followed by `make` to start a clean build.
   This approach is also recommended after everything is done, because some compiler warning appears
   only in clean builds.
