✨ Introduction

Memory management is a fundamental aspect of operating systems, crucial for optimizing performance and resource utilization. This project, Dynamic-Memory-Allocator-Simulator, is a C++ application designed to simulate and compare different memory allocation techniques: First-Fit, Best-Fit, and Worst-Fit. By visualizing how these algorithms allocate and deallocate memory, users can gain a deeper understanding of their memory usage and fragmentation efficiency.

🚀 Features

• Dynamic Technique Selection: Choose between First-Fit, Best-Fit, and Worst-Fit allocation techniques at runtime.
• Customizable Memory Partitions: Enter and modify memory partition sizes dynamically during execution.
• Visual Representation: View memory blocks and their allocation status through tables and color-coded indicators.
• Performance Metrics: Measure and compare the efficiency of each allocation technique regarding memory usage and fragmentation.
• Deallocation Support: Simulate real-world scenarios by freeing up allocated memory blocks.

📚 Installation

Prerequisites

• C++ Compiler: Ensure you have a C++17 compatible compiler installed (e.g., g++, clang++).
• CMake: Recommended for building the project.
• Windows OS: The current implementation utilizes Windows-specific libraries for console handling.

Steps

1. Clone the Repository

   git clone https://github.com/3bbaas/Dynamic-Memory-Allocator-Simulator.git

2. Configure Cmake file

   cmake_minimum_required(VERSION 3.30)
   project(Dynamic_Memory_Allocator_Simulator)
   
   set(CMAKE_CXX_STANDARD 23)
   
   include_directories(include)
   include_directories(include/Allocation)
   
   add_executable(Dynamic_Memory_Allocator_Simulator
   src/Allocation/BestFit.cpp
   src/Allocation/FirstFit.cpp
   src/Allocation/WorstFit.cpp
   src/Application.cpp
   src/ConsoleHandler.cpp
   src/UI.cpp
   main.cpp)

3. Navigate to the Project Directory

   cd Dynamic-Memory-Allocator-Simulator

4. Build the Project

   • Using Cmake

     mkdir build
     cd build
     cmake ..
     make

   • Alternatively, compile manually:

     g++ main.cpp src/*.cpp src/Allocation/*.cpp -o MemoryAllocatorSimulator 

5. Run the Application

   ./MemoryAllocatorSimulator

👥 Usage

Upon running the application, you will be greeted with a dynamic console interface where you can:

1. Update Partition Values (Admins Only)

   • Requires admin credentials to modify memory partition sizes.

2. Use Default Partitions

   • Proceed with predefined memory partitions or enter custom ones.

3. Choose Allocation Technique

   • Select between First-Fit, Best-Fit, and Worst-Fit to allocate memory for processes.

4. Allocate and Deallocate Processes

   • Add new processes with specific memory requirements.
   • Free up memory by deallocating existing processes.

5. Visualize Memory Allocation

   • View memory blocks as tables with color-coded statuses indicating allocated or free spaces.
