Ques:- What is object-oriented programming (OOP) and what are its key principles
Right Answer:
Object-oriented programming (OOP) is a programming paradigm that uses "objects" to represent data and methods to manipulate that data. The key principles of OOP are:

1. **Encapsulation**: Bundling data and methods that operate on that data within a single unit (object), restricting access to some components.
2. **Abstraction**: Hiding complex implementation details and showing only the essential features of an object.
3. **Inheritance**: Allowing a new class to inherit properties and behaviors (methods) from an existing class, promoting code reuse.
4. **Polymorphism**: Enabling objects to be treated as instances of their parent class, allowing methods to be used in different ways based on the object’s actual class.

1. **Planning**: Define the project scope and objectives.
2. **Requirements Analysis**: Gather and analyze user requirements.
3. **Design**: Create the architecture and design of the software.
4. **Implementation**: Write and compile the code.
5. **Testing**: Verify that the software works as intended and fix any issues.
6. **Deployment**: Release the software to users.
7. **Maintenance**: Provide ongoing support and updates as needed.
