Common Mistakes

Using a variable name that doesn't match the condition or increment part.

Using a variable name not declared in the loop.

The variable i is commonly used as the loop counter in Go for loops.

2fill in blank

medium

Complete the code to sum numbers from 1 to 5.

Go

sum := 0
for i := 1; i <= [1]; i++ {
    sum += i
}
fmt.Println(sum)

💡 Hint

Common Mistakes

Using a limit less than 5, so the sum misses the last number.

Using a limit greater than 5, causing extra iterations.

The loop should run until i is less than or equal to 5 to include 5 in the sum.

3fill in blank

hard

Fix the error in the loop condition to print even numbers from 0 to 8.

Go

for i := 0; i [1] 10; i += 2 {
    fmt.Println(i)
}

💡 Hint

Common Mistakes

Using greater than operator causing the loop to never run.

Using greater than or equal causing no output.

The loop should continue while i is less than 10 to print numbers up to 8.

4fill in blank

hard

Fill both blanks to create a loop that prints numbers from 5 down to 1.

Go

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

💡 Hint

Common Mistakes

Using less than operator causing the loop to never run.

Starting at 0 instead of 5.

The loop starts at 5 and continues while i is greater than 0, decreasing by 1 each time.

5fill in blank

hard

Fill all three blanks to create a loop that prints squares of numbers from 1 to 3.

Go

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