For loop as while in Go - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to create a loop that runs while i is less than 5.

Go

package main

import "fmt"

func main() {
    i := 0
    for [1] {
        fmt.Println(i)
        i++
    }
}

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

Ai < 5

Bi <= 5

Ci > 5

Di == 5

3 left

💡 Hint

Common Mistakes

Using 'i > 5' which never runs the loop initially.

Using 'i == 5' which runs only when i equals 5.

The condition i < 5 makes the loop run while i is less than 5.

2fill in blank

medium

Complete the code to print numbers from 1 to 3 using a for loop as while.

Go

package main

import "fmt"

func main() {
    i := 1
    for [1] {
        fmt.Println(i)
        i++
    }
}

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

Ai < 3

Bi <= 3

Ci >= 3

Di == 3

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'i < 3' which stops before printing 3.

Using 'i == 3' which runs only once when i equals 3.

The condition i <= 3 makes the loop run while i is 1, 2, and 3.

3fill in blank

hard

Fix the error in the loop condition to run while count is less than 4.

Go

package main

import "fmt"

func main() {
    count := 0
    for [1] {
        fmt.Println(count)
        count++
    }
}

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

Acount >= 4

Bcount > 4

Ccount < 4

Dcount == 4

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'count > 4' which never runs the loop initially.

Using 'count == 4' which runs only once when count equals 4.

The condition count < 4 runs the loop while count is 0, 1, 2, and 3.

4fill in blank

hard

Fill both blanks to create a loop that prints numbers from 2 to 6.

Go

package main

import "fmt"

func main() {
    num := 2
    for [1] {
        fmt.Println(num)
        num [2]
    }
}

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

Anum <= 6

Bnum < 6

C++

D++num

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'num < 6' which stops before printing 6.

Using '++num' which is invalid syntax in Go.

The condition num <= 6 keeps the loop running until 6. The increment num++ increases num by 1 each time.

5fill in blank

hard

Fill all three blanks to create a loop that prints even numbers from 0 to 4.

Go

package main

import "fmt"

func main() {
    i := 0
    for [1] {
        fmt.Println(i)
        i [2] 2
    }
}

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

Ai <= 4

B+=

C-=

D<=

Attempts:

3 left

💡 Hint

Common Mistakes

Using '<=' as an operator in the increment step.

Using '-=' which decreases i instead of increasing.

The condition i <= 4 runs the loop while i is 0, 2, and 4. The operator += adds 2 to i each time.
