What does the continue statement do inside a loop?

1. It breaks the loop completely.

2. It skips the current iteration.

3. It triggers a return.

4. It calls another function.

The correct answer is: It skips the current iteration.

The continue statement in a loop is designed to skip the current iteration and move to the next iteration immediately. When encountered, it signals the loop to bypass any code that follows it within the loop body for that specific iteration and continues with the next iteration. This functionality is particularly useful in scenarios where certain conditions need to be checked, and if those conditions are met, it's preferable to skip the remaining code for that iteration without terminating the loop entirely. For example, if you have a list of numbers and you want to print all numbers except for the even ones, you can use the continue statement to skip over the even numbers and proceed with the next number in the sequence. In contrast, breaking the loop completely or triggering a return would not allow for further iterations, and calling another function signifies a different operation that does not adhere to controlling the flow within the loop itself. Thus, the continue statement is specifically about skipping to the next loop cycle.
