Features
Calculator-Style Input
Implements an intuitive input flow that mirrors the behavior of a traditional desktop calculator.
Sequential Operations
Supports chained arithmetic operations without requiring operator precedence, matching the behavior of the Windows Calculator.
Robust Error Handling
Gracefully detects and handles invalid operations such as division by zero and integer overflow without crashing.
State-Based Calculation Engine
Maintains calculation state between button presses, enabling continuous calculations and repeated equals operations.
Why it was built
Desktop Calculator is a Windows Forms application that recreates the functionality of a traditional desktop calculator. The project focuses on event-driven programming, state management, arithmetic processing, and responsive user interaction. Rather than evaluating mathematical expressions, the application processes user input incrementally, replicating the behavior of standard calculator software while ensuring reliable error handling and a consistent user experience.
Tech stack
