📝 Note Manager with JSON Persistence (C++)

A lightweight C++ project to manage notes using smart pointers (shared_ptr, weak_ptr) and JSON file persistence. Notes are cached for recent access and automatically cleaned up when deleted.

🚀 Features

Add and view notes
Recent notes caching (with automatic cleanup of expired pointers)
Save and load notes from a JSON file
Uses shared_ptr and weak_ptr smart pointers
Minimal and easy to understand codebase

🛠 Technologies

C++17
Smart Pointers: shared_ptr, weak_ptr
STL: vector, deque, fstream, algorithm
JSON Parsing: custom or 3rd-party (e.g., nlohmann/json) (mention what you use)
