"Smart Wallet System" Assignment

Create a smart wallet system platform in C++ on Linux. Clients should be able to submit their info to the bank system and do transactions on their accounts.

Build and run

cmake -Bbuild . -DCMAKE_BUILD_TYPE=Debug
cmake --build build -j
./build/bin/Debug/Server-App &
./build/bin/Debug/Client-App &

Assumptions

1. Deposit/Withdrawal/Updating Info are undoable
2. No negative deposit/withdrawal
3. Server persists its data on disk, and loads it on startup
4. Clients have to login using their ID or register a new account
5. Undo/redo works similar to text editors:
   • Undo until the first event is undone
   • Redo until the last event is redone
   • Adding an event in the middle of an undo sequence begins another sequence from that point on

Server

1. Receive client info
2. Auto-generate account ID for new clients ($0 initial balance)
3. Save received info
4. Display candidate info
   • Status bar showing client name
   • Multi-line text box
   • Log file of all transactions done
5. Process transaction on client account
6. Send amount of money to client
7. (BONUS) Analyze clients info, show statistics and graphs of all accounts ✅
8. (BONUS) Undo/redo transaction when requested from client ✅
