A simple C++ console application that calculates the area of circle, square, and rectangle shapes.
Built using Object-Oriented Programming (OOP) principles like inheritance, abstraction, and polymorphism. It also includes input validation and loops until the user decides to exit.
- Calculate area for:
- Circle: π × r²
- Square: width²
- Rectangle: width × height
- Input validation: handles invalid shape options
- Simple text-based interface
- Loops until the user chooses to quit
- Clean program exit
- Compile the program:
g++ area_calculator.cpp -o area_calculator
./area_calculator
Here’s an example of the program running with valid and invalid inputs:
