Function Definition

What is a function in programming?

• A function in programming is a block of code that performs a specific task.

• A function in programming is a comment that explains the code.

• A function in programming is a variable that stores data.

• A function in programming is a loop that repeats a set of instructions.

Explain the purpose of using functions in code.

• Functions slow down the execution of the code.

• Functions are used to increase redundancy in the code.

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

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

What are the key components of a function?

• function name, parameters, return type, function body, arguments

• function name, parameters, return type, function body, output

• function name, parameters, return type, function body, return statement

• function name, parameters, return type, function body, return statement

How do functions help in organizing code?

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

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

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

• Functions do not allow code reusability.

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

• A function declaration and a function call are the same thing.

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

• A function declaration defines the function, while a function call executes the function.

• A function declaration executes the function, while a function call defines the function.

Why is it important to define parameters in a function?

• Defining parameters in a function is important to confuse the programmer

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

• Defining parameters in a function is important to increase errors

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

Can a function return a value? Explain.

• No

• Yes

• Sometimes

• Maybe

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

• The return statement is optional and can be omitted in functions

• The return statement is used to print output to the console

• The return statement is used to define variables within the function

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

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

• Use the function only once in the entire program

• Copy and paste the function code multiple times

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

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

Provide an example of a simple function in a programming language.

• def add_numbers(num1, num2): return num1 + num2

• def divide_numbers(num1, num2): return num1 / num2

• def multiply_numbers(num1, num2): return num1 * num2

• def subtract_numbers(num1, num2): return num1 - num2
