Continue statement - 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 moves to the next iteration immediately.

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

Consider this code snippet:<br>

for(int i = 0; i < 5; i++) { if(i == 2) continue; printf("%d ", i); }

<br>What will be the output?

The output will be: 0 1 3 4 <br>The number 2 is skipped because continue skips printing when i == 2.

intermediate

Why might you use continue instead of if-else inside a loop?

Using continue can make code cleaner by avoiding nested if-else blocks and clearly skipping unwanted cases.

What does the continue statement do inside a loop?

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

B Exits the loop completely

C Pauses the loop until user input

D Restarts the entire program

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

In which loop(s) can you use continue in C?

A Only <code>for</code> loops

B Only <code>while</code> loops

C Only <code>do-while</code> loops

D <code>for</code>, <code>while</code>, and <code>do-while</code> loops

continue works in all three loop types: for, while, and do-while.

What happens if continue is used inside nested loops?

A It exits all loops immediately

B It skips the rest of all loops

C It skips the rest of the innermost loop only

D It causes a compile error

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

What will this code print?<br>

for(int i=0; i<3; i++) { if(i==1) continue; printf("%d", i); }

A 012

B 02

C 123

D 13

When i==1, continue skips printing. So only 0 and 2 are printed.

Why might continue improve code readability?

A It avoids nested <code>if-else</code> blocks by skipping unwanted cases

B It automatically documents the code

C It replaces all <code>break</code> statements

D It makes loops run faster

continue helps avoid deep nesting by skipping certain cases early, making code easier to read.

Explain how the continue statement works inside a loop and give a simple example.

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

Describe a situation where using continue makes your loop code cleaner compared to using if-else.

Imagine you want to ignore some values and only process others inside a loop.
