A C++ command-line scientific calculator that supports arithmetic operations, trigonometric functions, powers, logarithms, and square roots — built from scratch using core C++ and the <cmath> library.
- Basic arithmetic:
+,-,*,/ - Trigonometric functions:
sin,cos,tan(input in degrees) - Power and square root calculations
- Natural and base-n logarithms
- Error handling (e.g., divide by zero, invalid inputs)
- Modular and readable OOP-based structure
- Object-oriented programming in C++
- Function overloading and input validation
- Using built-in math functions from
<cmath> - Command-line input handling
