Cash Memo System
Receipt generation with OOP design
Professional console-based C++ receipt/memo system demonstrating real-world OOP patterns. Features dynamic data entry, formatted output, input validation, and Makefile build system. Separates concerns into helper classes: Item, Date, Address, CellNumber, Name, ShopDetails, ReceiptNo.
Why it mattered
Mastered class composition, encapsulation, and professional C++ project structure
