Continue statement in C++ - Cheat Sheet & Quick Revision

Recall & Review

beginner

What does the continue statement do in a loop?

It skips the rest of the current loop iteration and immediately starts the next iteration of the loop.

beginner

In which types of loops can you use the continue statement in C++?

You can use continue in for, while, and do-while loops.

intermediate

What happens if continue is used inside a nested loop?

It only affects the innermost loop where it is used, skipping to the next iteration of that loop.

beginner

True or False: The continue statement exits the entire loop.

False. continue skips to the next iteration but does not exit the loop. The break statement exits the loop.

Example: What will be the output of this code?<br>

for (int i = 1; i <= 5; i++) {
  if (i == 3) continue;
  std::cout << i << " ";
}

The output will be: 1 2 4 5 <br>The number 3 is skipped because when i == 3, continue skips printing it.

What does the continue statement do inside a loop?

A Pauses the loop until user input

B Exits the entire loop immediately

C Skips the rest of the current iteration and starts the next iteration

D Restarts the program

The continue statement skips the remaining code in the current loop iteration and moves to the next iteration.

In a for loop, what happens after a continue statement is executed?

A The loop variable resets to zero

B The loop ends immediately

C The program crashes

D The loop variable is updated and the next iteration begins

After continue, the loop updates the loop variable (like incrementing) and starts the next iteration.

Can continue be used in a while loop?

A Yes, it skips to the next iteration

B No, it only works in <code>for</code> loops

C Only if the loop has a break

D Only inside functions

continue works in all loop types including while loops.

What is the difference between continue and break?

A <code>continue</code> exits the loop; <code>break</code> skips iteration

B <code>continue</code> skips to next iteration; <code>break</code> exits the loop

C Both do the same thing

D Neither affects the loop

continue skips the rest of the current iteration, while break stops the loop completely.

If continue is used inside nested loops, which loop does it affect?

A Only the innermost loop where it appears

B All loops at once

C Only the outermost loop

D It causes an error

continue affects only the loop it is directly inside.

Explain how the continue statement changes the flow inside a loop.

Think about what happens when you want to skip some steps but keep looping.

Describe a real-life example where using continue in a loop would be helpful.

Imagine sorting mail and skipping junk mail without stopping the whole process.
