# 🧠 Memory Management Simulator
🚀 A modern C++ simulator that models memory allocation using **First-Fit** and **Best-Fit** strategies. Designed to emulate real-world memory management in operating systems, this project features a runtime strategy switch, stress testing, data export, and optional unit testing via GoogleTest.
---
## ✨ Features
- 🔁 **Allocation Strategies**: Switch between First-Fit and Best-Fit at runtime
- 📊 **Exportable Logs**: Memory block states saved to CSV for analysis
- 🧪 **Random Stress Testing**: Dynamically simulate fragmentation and load
- 💾 **Save/Load State**: Resume memory states using file I/O
- 🧠 **CLI-Based UI**: Intuitive and interactive user interface
- ✅ **Unit Tests**: Written using GoogleTest (via `vcpkg`)
- 🧵 **Modular Design**: Clear separation of core logic and utilities
---
## 🔧 Getting Started
### 📦 Prerequisites
- CMake ≥ 3.16
- C++17 compiler (MSVC, GCC, or Clang)
- [vcpkg](https://github.com/microsoft/vcpkg) (for dependency management)
### 🛠️ Build Instructions
```bash
git clone https://github.com/Opikadash/memory-management-simulator.git
cd MemoryManagementSimulator
cmake -B build
cmake --build build
````
### ✅ Run the Simulator
```bash
./build/simulator
```
---
## 🧪 Running Unit Tests (Optional)
Install GoogleTest using [vcpkg](https://github.com/microsoft/vcpkg):
```bash
vcpkg install gtest
```
Then build with tests:
```bash
cmake -DENABLE_TESTING=ON -B build
cmake --build build
cd build && ctest
```
---
## 📈 Visualize Memory Logs
```bash
python scripts/visualize_memory.py data/memory_log.csv
```
Creates a time-series graph of allocation and fragmentation over time.
