What is a variable in programming?

• A comment within the code

• A symbolic name for a value that can change

• A function that performs a specific task

• A fixed value that cannot be changed

Give an example of a data type in programming.

• character

• float

• boolean

• integer

Explain the concept of if-else statement.

• If-else statement can only be used for numerical comparisons.

• The concept of if-else statement involves executing different blocks of code based on a specified condition.

• The if-else statement can have multiple else blocks.

• The if-else statement always executes both blocks of code.

What is the purpose of a loop in programming?

• To slow down the program

• To repeatedly execute a block of code

• To skip executing a block of code

• To confuse the programmer

How do functions help in organizing code?

• Functions make the code more complex and harder to understand.

• Functions do not allow code reusability.

• Functions increase the size of the program without any benefit.

• Functions break down a program into smaller, reusable blocks of code.

Differentiate between arrays and lists.

• Arrays can contain elements of different data types, while lists have a fixed data type.

• Arrays and lists are the same thing.

• Arrays are fixed in size and have a specific data type, while lists can dynamically grow and contain elements of different data types.

• Arrays can dynamically grow in size, while lists are fixed in size.

What is the syntax for declaring a variable in Python?

• variable_name : value

• variable_name = value =

• value = variable_name

• variable_name = value

Describe the concept of switch case.

• Switch case is only applicable in object-oriented programming

• Switch case is used for sorting data in a database

• Switch case is a control structure in programming that evaluates an expression and executes different blocks of code based on the value of that expression.

• Switch case is a loop structure in programming

Why are functions considered reusable in programming?

• Functions increase the complexity of the code

• Functions encapsulate a set of instructions that can be called multiple times from different parts of a program without the need to rewrite the code.

• Functions are only usable once in a program

• Functions can only be called from one specific part of a program

How are arrays indexed in most programming languages?

• Starting from -1

• Starting from 0

• Starting from 1

• Starting from A
