How does the concept of polymorphism in Object-Oriented Programming enhance code reusability?
- It allows objects of different classes to be treated as objects of a common base class.
- It eliminates the need for inheritance.
- It promotes static binding of methods.
- It restricts the ability to extend and modify classes.
Polymorphism in OOP enhances code reusability by allowing objects of different classes to be treated as objects of a common base class. This enables more flexible and extensible code as you can work with various objects without knowing their specific types, which encourages reuse and simplifies code maintenance.
A software development team notices that the requirements are changing frequently. Which limitation of traditional SDLC is this situation highlighting, and how can Agile methodologies provide a solution?
- Inflexibility to changing requirements
- Lack of customer involvement throughout development
- Lack of documentation and planning
- Poor quality of code produced
The changing requirements highlight the inflexibility of traditional SDLC models. Agile methodologies provide a solution through iterative development and frequent customer feedback, allowing adaptation to evolving requirements.
The _____ phase in SDLC involves creating detailed specifications about how the software system should function and look.
- Analysis
- Design
- Implementation
- Requirements
The Design phase in SDLC involves creating detailed specifications about how the software system should function and look, including user interfaces and system architecture.
In _______ programming, functions are treated as first-class citizens, allowing them to be passed as arguments and returned from other functions.
- Functional
- Imperative
- Object-Oriented
- Procedural
In functional programming, functions are treated as first-class citizens, which means they can be passed as arguments and returned from other functions. This allows for powerful and flexible programming techniques.
The _____ phase of the SDLC involves translating the software design into source code.
- Development
- Maintenance
- Planning
- Testing
The Development phase is where the software design is transformed into source code, where the actual development of the software takes place.
How can incorporating Continuous Integration (CI) enhance the code review process?
- It automates testing and code integration, improving code review
- It delays the code review process
- It introduces manual and time-consuming processes
- It prevents collaboration between team members
Continuous Integration (CI) automates testing and code integration, which enhances the code review process by ensuring that the code is always in a testable state. It fosters collaboration and accelerates the review process.
What type of document is used to formally describe the requirements of a software system?
- Project schedule
- Software design document
- Software requirement specification (SRS)
- User manual
A Software Requirement Specification (SRS) is the document used to formally describe the requirements of a software system. It details the functional and non-functional requirements, constraints, and features of the software to be developed.
A team is working on a project with frequent requirement changes. What would be the advantages and disadvantages of using automated testing in this scenario?
- Advantages: Early bug detection, Disadvantages: Test maintenance overhead.
- Advantages: Faster testing, Disadvantages: Incomplete test coverage.
- Advantages: Greater flexibility, Disadvantages: Increased development time.
- Advantages: Reduced development time, Disadvantages: Frequent test failures.
In a project with frequent requirement changes, automated testing can provide early bug detection, helping the team adapt to changes more efficiently. However, it may require continuous test maintenance as requirements evolve, which can introduce some overhead.
In Object-Oriented Programming, the concept of _______ allows an object to take on multiple forms.
- Abstraction
- Encapsulation
- Inheritance
- Polymorphism
Polymorphism in Object-Oriented Programming allows an object to take on multiple forms. It enables objects of different classes to be treated as objects of a common superclass, promoting flexibility and extensibility in software design.
_____ management involves systematically tracking, testing, and applying updates and patches to software applications and systems.
- Change
- Configuration
- Patch
- Risk
Change management involves systematically tracking, testing, and applying updates and patches to software applications and systems to ensure the stability and security of the environment.
