Why loop control is required in Go - Test Your Understanding

Practice - 5 Tasks

1fill in blank

easy

Complete the code to print numbers from 1 to 5 using a for loop.

Go

for i := 1; i <= [1]; i++ {
    fmt.Println(i)
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using 0 or 6 as the loop limit causes incorrect output or extra iterations.

The loop should run until i is less than or equal to 5 to print numbers 1 to 5.

2fill in blank

medium

Complete the code to skip printing the number 3 inside the loop.

Go

for i := 1; i <= 5; i++ {
    if i == [1] {
        continue
    }
    fmt.Println(i)
}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using the wrong number in the if condition causes the wrong iteration to be skipped.

The continue statement skips the current iteration when i equals 3, so 3 is not printed.

3fill in blank

hard

Fix the error in the loop to stop printing numbers when i equals 4.

Go

for i := 1; i <= 5; i++ {
    if i == [1] {
        break
    }
    fmt.Println(i)
}

💡 Hint

Common Mistakes

Using a number other than 4 causes the loop to stop too early or too late.

The break statement stops the loop when i equals 4, so numbers 1 to 3 are printed.

4fill in blank

hard

Fill both blanks to create a loop that prints even numbers from 2 to 10.

Go

for i := [1]; i <= 10; i += [2] {
    fmt.Println(i)
}

💡 Hint

Common Mistakes

Starting at 1 or increasing by 1 prints odd numbers or all numbers.

Start from 2 and increase i by 2 each time to print even numbers from 2 to 10.

5fill in blank

hard

Fill all three blanks to create a loop that prints numbers from 10 down to 1.

Go

for i := [1]; i [2] 1; i [3] {
    fmt.Println(i)
}

💡 Hint

Common Mistakes

Using incorrect operators or starting point causes infinite loop or wrong output.

The loop starts at 10, continues while i is greater than or equal to 1, and decreases i by 1 each time.
