G12AM_WSheet_Sprint 2.3 Iteration

What is the main purpose of iteration in programming?

• To stop the program

• To create new variables

• To repeat a block of code

• To execute code only once

Which loop executes a block of code a specific number of times?

• While loop

• For loop

• Do-while loop

• If statement

What is an infinite loop?

• A loop that stops immediately

• A loop that checks conditions

• A loop that runs a set number of times

• A loop that runs forever

What does a 'do-while' loop do differently from a 'while' loop?

• Checks the condition before executing

• Executes at least once

• Does not execute at all

• Only runs if the condition is false

Which loop is best for repeating a process until a condition is met?

• Repeat loop

• Do-while loop

• While loop

• For loop

What is the purpose of nested iterations?

• To create a single loop

• To check conditions

• To loop inside another loop

• To stop the program

What happens if a loop condition never becomes true?

• The loop runs a set number of times

• The loop runs once

• The loop runs forever

• The loop stops immediately

What is the output of a loop that sums numbers from 1 to 1000?

• 1000

• 500

• 500500

• 1001

Which of the following is NOT a type of loop?

• For loop

• While loop

• Switch loop

• Do-while loop

What is the main benefit of using iteration in programming?

• To reduce code length

• To create errors

• To make code longer

• To stop the program
