• ✅ Heap (priority_queue)
• ✅ Hash Map (unordered_map)
• ✅ Dynamic Array (vector)
• ✅ Object-Oriented Programming

🔧 Technologies Used

C++, STL, priority_queue, unordered_map, vector, custom comparator

🚀 Features

• Add posts per user
• Follow specific users
• Show top trending posts based on likes and recency

📌 Sample Output

Top 3 posts from followed users: Post ID: 4 | Author: Alice | Likes: 150 | Time: 15 | Content: Check out my new blog Post ID: 1 | Author: Alice | Likes: 100 | Time: 10 | Content: Hello World! Post ID: 5 | Author: Bob | Likes: 95 | Time: 16 | Content: Weekend Vibes

🧠 Data Structures Used

• unordered_map<string, vector<Post>> – to store posts per user
• priority_queue<Post> – to rank posts by popularity

✅ How to Run

g++ main.cpp -o feed
./feed
