Heap_Manager

Heap Manager made in C language as Project For DSA-II Course.

About Project

• Efficient and FastMemory Management is very important topic in industry.
• We implement our own Heap Manager here which take care of memory allocation and deallocation in efficient way.
• The complete Project is implemented in C language.
• We implement here Malloc,Free,Calloc and Realloc calls here in this project.
• Data Structures used:
  1. Doubly Linked List
  2. Heap data Structure

Usage

Make sure you have gcc installed You can check by typing the following in your terminal

$ gcc --version

Download the repository (May be use git clone or download zip folder of project).

$ git clone  https://github.com/Siddhesh4501/Heap_Manager.git

Copy mm.h, mm.c, heap.h and heap.c from the src/ folder to your project directory and include mm.h in your main file instead of <stdlib.h> library

#include "mm.h"

Don't forget to add mm_init() at the start of your main() function or any other file in which use include mm.h file.

mm_init()

Compile program by using

gcc yourfiles.c mm.c heap.c -o final

Execute ./final to see output of your code.

./final
