📡 In-Memory Event Stream Engine

A C project that implements an event stream using singly linked lists.
Perfect for learning dynamic memory, pointer manipulation, and modular C design.

---

🚀 Features

• Add events dynamically with id, source, and payload
• Print full stream contents
• Search for events by ID
• Delete specific events by ID
• Reverse the stream order
• Fully interactive CLI with memory safety

📦 File Structure

├── event.h          # Structure and function declarations
├── event.c          # Core logic: add, delete, search, reverse
├── event_stream.c   # Main program with menu UI
├── Makefile         # Easy build

---

🧪 Sample Run

--- Event Stream Menu ---
1. Add Event
2. Print Stream
3. Search Event by ID
4. Delete Event by ID
5. Reverse Stream
6. Exit
Enter your choice: 2

Event Stream:
Event ID: 6, Source: sensor-3, Payload: Temperature: 25°C
Event ID: 5, Source: light-2, Payload: Light turned on
Event ID: 3, Source: sensor-2, Payload: Humidity: 46%
Event ID: 2, Source: camera-1, Payload: Motion detected

🛠 Build and Run

🔧 Requirements

• GCC compiler (e.g., gcc or clang)
• Make utility (recommended)

---

🔨 Build

To build using the provided Makefile:

make

Or compile manually without Makefile:

gcc -o event_stream event.c event_stream.c

---

▶️ Run the Program

./event_stream

You'll see an interactive CLI menu:

--- Event Stream Menu ---
1. Add Event
2. Print Stream
3. Search Event by ID
4. Delete Event by ID
5. Reverse Stream
6. Exit
Enter your choice: _

---

🧼 Clean the Build

To remove the compiled executable:

make clean

Or manually:

rm event_stream
