Ruby Object-Oriented Programming: Build a Basic Calculator

Want to understand how to structure your code for reusability and maintainability? Object-oriented programming (OOP) in Ruby offers a powerful way to organize your applications. This course will guide you through the process of applying core OOP principles to build practical applications, transforming your approach to coding in Ruby. You'll gain the confidence to design and implement your own modular and well-structured programs. What you'll learn: * Understand the foundational concepts of object-oriented programming, including classes, objects, and encapsulation. * Build and instantiate Ruby classes, defining their attributes and behaviors using methods. * Apply principles of abstraction to create clean, easy-to-use interfaces for your objects. * Implement basic error handling mechanisms to make your applications more resilient to unexpected input. * Practice writing simple test cases to ensure the correctness and reliability of your Ruby code. * Design and construct a fully functional basic calculator application using an OOP approach. The course begins with an introduction to key OOP terminology and concepts, then progresses to practical application through the development of a calculator. You will learn by reading explanations and working through code examples and exercises. This course is designed for absolute beginners to Ruby and object-oriented programming. No prior programming experience is required. Begin your journey into object-oriented Ruby programming today.
