Looping & Functions C++

What is the purpose of loops in C++?

• To execute code only once

• To repeat a set of statements multiple times

• To store values in memory

• To declare variables

Which of the following is a pre-test loop in C++?

• while

• do-while

• switch

• for

What is the difference between a while loop and a do-while loop?

• while is post-test, do-while is pre-test

• while loop checks the condition before executing, do-while checks after execution

• do-while loop never executes

• They behave the same way

Which of the following loops guarantees at least one execution of the loop body?

• for

• while

• do-while

• if

What is an event-controlled loop?

• A loop that runs for a specific number of iterations

• A loop that continues until a certain event or condition occurs

• A loop that runs based on user input

• A loop that runs indefinitely

Which loop structure is most suitable for iterating a known number of times?

• for loop

• while loop

• do-while loop

• switch statement

What does the break statement do in a loop?

• It skips the current iteration

• It stops the loop and exits immediately

• It restarts the loop

• It increments the loop variable

What is the purpose of the continue statement in a loop?

• To terminate the loop

• To skip the remaining code in the current iteration and move to the next iteration

• To restart the loop

• To exit the program

Which of the following is a valid for loop structure in C++?

• for (int i = 0; i < 10; i++)

• for (int i++; i < 10; i = 0)

• for (i = 0, i < 10, i++)

• for (int i = 0; i++)

What is the output of the following code: for (int i = 0; i < 3; i++) { cout << i; }?

• 012

• 123

• 345

• 000
