It's necessary to use OO programming languages rather than routine based languages to overcome the problem of huge codes.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
Object-oriented (OO) programming languages are designed to handle complex code structures more efficiently compared to routine-based languages. OO languages provide features like encapsulation, inheritance, and polymorphism, which help in organizing and managing large codebases. These features enable code reusability, modular development, and easier maintenance. In contrast, routine-based languages lack these features, making it harder to manage and scale large projects. Therefore, using OO programming languages is necessary to overcome the problem of huge codes and improve code quality and maintainability.Rate this question:

- A.
A-idioms
- B.
B-queries
- C.
C-prototypes
- D.
D-suggestions
Correct Answer
C. C-prototypesExplanation
To engineer the illusion of simplicity, developers must present prototypes. Prototypes are early versions or models of a product that simulate its functionality and design. By creating prototypes, developers can gather feedback from users and make necessary improvements before the final product is developed. Prototypes allow developers to visually demonstrate their ideas, making it easier for users to understand and provide feedback. This iterative process helps in refining the product and creating a user-friendly experience, ultimately achieving the illusion of simplicity.Rate this question:
