Practice - 5 Tasks

1fill in blank

easy

Complete the code to break the loop when the counter reaches 3.

Rust

let mut count = 0;
loop {
    count += 1;
    if count == [1] {
        break;
    }
}
println!("Count stopped at {}", count);

💡 Hint

Common Mistakes

Using a number other than 3 causes the loop to break too early or too late.

The loop breaks when count equals 3, stopping the loop at the right time.

2fill in blank

medium

Complete the code to break the loop when the input number is zero.

Rust

let mut input = 5;
loop {
    if input == [1] {
        break;
    }
    input -= 1;
}
println!("Loop ended because input is zero.");

💡 Hint

Common Mistakes

Using 1 or -1 instead of 0 causes the loop to break at the wrong time.

The loop breaks when input reaches zero, stopping the countdown.

hard

Fix the error in the loop to break when the variable reaches 4.

Rust

let mut num = 0;
loop {
    num += 1;
    if num == [1] {
        break;
    }
}
println!("Stopped at {}", num);

💡 Hint

Common Mistakes

Using 3 or 5 causes the loop to break too early or too late.

The loop should break when num equals 4, so the correct value is 4.

4fill in blank

hard

Fill both blanks to create a loop that breaks when the counter is less than 2.

Rust

let mut counter = 5;
loop {
    counter -= 1;
    if counter [1] [2] {
        break;
    }
}
println!("Counter stopped at {}", counter);

💡 Hint

Common Mistakes

Using '==' instead of '<' changes the stopping condition.

Using 3 instead of 2 breaks the loop at the wrong time.

The loop breaks when counter < 2, so the operator is < and the number is 2.

5fill in blank

hard

Fill all three blanks to break the loop when the value is greater than 7 and print the value.

Rust

let mut value = 0;
loop {
    value += 2;
    if value [1] [2] {
        break;
    }
}
println!("Value is [3]", value);

💡 Hint

Common Mistakes

Using '<' instead of '>' changes the condition.

Forgetting '{}' in the print statement causes no value to show.

The loop breaks when value > 7. The print uses {} to show the value.
