What is an infinite loop and how does loop control prevent it?
An infinite loop runs forever because its end condition is never met. Loop control ensures the loop condition changes so the loop can stop.

Why do we need loop control in a program?
✗ Incorrect
Loop control stops loops from running endlessly, preventing program crashes.
Which statement can be used inside a loop to exit it immediately?
✗ Incorrect
The 'break' statement exits the loop immediately.
What happens if the loop variable is never updated inside a loop?
✗ Incorrect
Without updating, the loop condition never changes, causing an infinite loop.
Which of these is NOT a loop control structure in C?
✗ Incorrect
'repeat' is not a valid loop structure in C.
What does the 'continue' statement do inside a loop?
✗ Incorrect
'continue' skips the current iteration and moves to the next one.
