CUET PG 2021 — Computer PYQ

CUET PG | Computer | 2021

Which among the following is the language which supports classes but not polymorphism?

Choose the correct answer:

Explanation

Solution Logic

Programming languages ko unke Object-Oriented features ke aadhar par do mukhya categories mein baata ja sakta hai:

Object-Oriented Programming (OOP): Yeh languages charon mukhya pillars ko support karti hain:

$\text{OOP} = \text{Encapsulation} + \text{Abstraction} + \text{Inheritance} + \text{Polymorphism}$

Udaharan: Java, C++, Python.
Object-Based Programming: Yeh languages Classes aur Objects ko toh support karti hain, lekin Inheritance ya Polymorphism (visheshkar Dynamic Polymorphism) ko puri tarah support nahi karti.

$\text{Object-Based} = \text{Classes/Objects} - \text{Inheritance/Polymorphism}$

Sahi Jawab (The Language)

Sahi jawab hai: Ada (Basic version) ya Visual Basic (Classic/Pre-.NET versions).

Halaanki, modern contexts mein aksar Visual Basic 6.0 ko iska sabse bada udaharan maana jata hai kyunki:

Isme Classes create ki ja sakti hain.
Isme Encapsulation hota hai.
Lekin isme True Inheritance aur Polymorphism (jaise Overriding) ka abhav hota hai.

FINAL ANSWER

Aisi language jo classes ko support karti hai lekin polymorphism ko nahi, use Object-Based Language kehte hain. Diye gaye options ke mutabik Ada ya Visual Basic iska sahi answer hoga.
