Calculator
A calculator app is a basic yet essential utility application that allows users to perform arithmetic and mathematical operations. In mobile app development, it's often used as a beginner project to learn core concepts of app design, logic implementation, and UI/UX.
Key Components:
User Interface (UI):
Buttons for digits (0-9) and operations (+, –, ×, ÷, =, etc.)
A display screen to show inputs and results
Optional advanced functions (%, √, sin, cos, etc. for scientific calculators)
Programming Logic:
Handlers for button clicks
A logic engine to parse and evaluate expressions
Memory to store temporary values for multi-step calculations
Tech Stack (for Mobile Apps):
Android (Java/Kotlin) or iOS (Swift)
Cross-platform frameworks like Flutter (Dart), React Native (JavaScript/TypeScript)
Development Concepts:
Event handling (e.g., tap listeners)
State management
Layout and positioning (grid for buttons)
Input validation and error handling
Advanced Features:
Scientific calculator mode
Voice input for calculations
Dark/light theme toggle
History of calculations
Why It's Useful in Learning:
Strengthens UI building skills
Teaches how to handle user input and output
Great for practicing conditional logic and state updates
