1fill in blank

easy

Complete the code to exit the loop immediately when i equals 3.

C++

for (int i = 0; i < 5; i++) {
    if (i == 3) {
        [1];
    }
    std::cout << i << std::endl;
}

💡 Hint

Common Mistakes

Using 'continue' instead of 'break' will skip the rest of the loop but not exit it.

The break statement exits the loop immediately when the condition is met.

medium

Complete the code to skip printing the number 2 inside the loop.

C++

for (int i = 0; i < 5; i++) {
    if (i == 2) {
        [1];
    }
    std::cout << i << std::endl;
}

💡 Hint

Common Mistakes

Using 'break' will stop the loop entirely, not just skip one iteration.

The continue statement skips the current loop iteration and moves to the next one.

hard

Fix the error in the code to return from the function when x is negative.

C++

void checkNumber(int x) {
    if (x < 0) {
        [1];
    }
    std::cout << "Number is non-negative" << std::endl;
}

💡 Hint

Common Mistakes

Using 'break' or 'continue' outside loops causes errors.

The return statement exits the function immediately.

4fill in blank

hard

Fill both blanks to create a loop that skips even numbers and stops when i reaches 7.

C++

for (int i = 0; i < 10; i++) {
    if (i [1] 2 [2] 0) {
        continue;
    }
    if (i == 7) {
        break;
    }
    std::cout << i << std::endl;
}

💡 Hint

Common Mistakes

Using wrong comparison operators or 'break' instead of 'continue'.

The condition i % 2 == 0 checks if i is even, and continue skips printing even numbers.

5fill in blank

hard

Fill all three blanks to create a function that returns the first positive number in an array or -1 if none found.

C++

int firstPositive(int arr[], int size) {
    for (int i = 0; i < size; i++) {
        if (arr[[1]] [2] 0) {
            [3] arr[i];
        }
    }
    return -1;
}

💡 Hint

Common Mistakes

Using wrong index or comparison, or forgetting to return the value.

We check each element with arr[i] > 0 and use return to exit the function immediately with the first positive number.
