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] 5; i++ {
    fmt.Println(i)
}

💡 Hint

Common Mistakes

Using '<' will stop before printing 5.

Using '>' or '>=' will cause the loop not to run.

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

2fill in blank

medium

Complete the code to sum numbers from 1 to 10 using a for loop.

Go

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

💡 Hint

Common Mistakes

Using '<' excludes 10 from the sum.

Using '>' or '>=' will not run the loop correctly.

The loop must include 10, so the condition should be i <= 10.

3fill in blank

hard

Fix the error in the loop condition to print even numbers from 2 to 10.

Go

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

💡 Hint

Common Mistakes

Using '<' excludes 10 from printing.

Using '>' or '>=' will cause the loop not to run.

The loop should continue while i is less than or equal to 10 to include 10.

4fill in blank

hard

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

Go

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

💡 Hint

Common Mistakes

Using '<=' will cause the loop to never run.

Using '++' will increase i and cause an infinite loop.

The loop should run while i is greater than or equal to 1, and decrement i each time using --.

5fill in blank

hard

Fill all three blanks to create a loop that prints only odd numbers from 1 to 9.

Go

for i := [1]; i [2] 9; i [3] {
    fmt.Println(i)
}

💡 Hint

Common Mistakes

Starting at 0 will print even numbers.

Using '<' excludes 9 from printing.

Incrementing by 1 prints all numbers, not just odd.

The loop starts at 1, runs while i is less than or equal to 9, and increments i by 2 to get odd numbers.
