2.

Explain the purpose of using functions in code.

a)

Functions slow down the execution of the code.

b)

Functions are used to increase redundancy in the code.

c)

Functions make the code more complex and harder to read.

d)

Functions help in organizing code, reducing redundancy, and improving modularity.

4.

How do functions help in organizing code?

a)

Functions make the code more complex and harder to understand.

b)

Functions increase the size of the code without any benefit.

c)

Functions break down a program into smaller, reusable parts, making the code more modular and easier to manage.

d)

5.

Describe the difference between a function declaration and a function call.

a)

b)

A function declaration is used for variables, while a function call is used for functions.

c)

6.

Why is it important to define parameters in a function?

a)

Defining parameters in a function is important to confuse the programmer

b)

Defining parameters in a function is important to slow down the execution

c)

Defining parameters in a function is important to increase errors

d)

Defining parameters in a function is important to pass values into the function for specific tasks and make it reusable.

a)

No

b)

Yes

c)

Sometimes

d)

Maybe

8.

What is the significance of the return statement in a function?

a)

The return statement is optional and can be omitted in functions

b)

The return statement is used to print output to the console

c)

The return statement is used to define variables within the function

d)

The return statement specifies the value that the function should return when called.

9.

How can functions be reused in different parts of a program?

a)

Use the function only once in the entire program

b)

Copy and paste the function code multiple times

c)

Define the function once and call it in different parts of the program.

d)

Define the function with different names in each part of the program

10.
