The symbol "?" belongs to which operator?
technology programming languages

  1. Conditional Operator

  2. Bitwise Operators

  3. Logical operators

  4. Relational Operator

Show answer
Correct Option: A
Explanation:

To solve this question, the user needs to have a basic understanding of the different types of operators used in programming languages.

The symbol "?" is known as the conditional operator.

Option A: Conditional Operator - This option is correct. The conditional operator, also known as the ternary operator, is represented by the symbol "?". It is a shorthand way of writing an if-else statement in a single line of code.

Option B: Bitwise Operators - This option is incorrect. Bitwise operators are used to perform operations on individual bits of a number. Examples include AND, OR, NOT, and XOR.

Option C: Logical Operators - This option is incorrect. Logical operators are used to combine multiple conditions. Examples include AND, OR, and NOT.

Option D: Relational Operator - This option is incorrect. Relational operators are used to compare two values. Examples include , <=, >=, ==, and !=.

Therefore, the answer is: A. Conditional Operator

Encapsulation is the process of basing one class on another.

technology programming languages

  1. True

  2. False

Show answer
Correct Option: B

AI Explanation

To answer this question, you need to understand the concept of encapsulation.

Encapsulation is a fundamental principle of object-oriented programming (OOP) that involves bundling data and the methods that operate on that data within a single unit, known as a class. The purpose of encapsulation is to hide the internal details of the object and provide a public interface through which other objects can interact with it.

The statement "Encapsulation is the process of basing one class on another" is incorrect. Encapsulation is not about one class being based on another. It is about combining data and methods into a single unit (class) to achieve data hiding and abstraction.

Therefore, the correct answer is B) False.
