If–else statement in Go - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to print "Even" if the number is divisible by 2.

Go

package main
import "fmt"
func main() {
    num := 4
    if num [1] 2 == 0 {
        fmt.Println("Even")
    }
}

💡 Hint

Common Mistakes

Using division operator '/' instead of remainder operator '%'.

Using multiplication '*' or addition '+' operators incorrectly.

The % operator gives the remainder. If num % 2 == 0, the number is even.

2fill in blank

medium

Complete the code to print "Positive" if the number is greater than zero.

Go

package main
import "fmt"
func main() {
    num := 10
    if num [1] 0 {
        fmt.Println("Positive")
    }
}

💡 Hint

Common Mistakes

Using '<' which checks if number is less than zero.

Using '==' which checks for equality.

The operator > checks if num is greater than zero.

3fill in blank

hard

Fix the error in the if–else statement to print "Odd" when the number is not divisible by 2.

Go

package main
import "fmt"
func main() {
    num := 7
    if num % 2 == 0 {
        fmt.Println("Even")
    } [1] {
        fmt.Println("Odd")
    }
}

💡 Hint

Common Mistakes

Using 'elseif' or 'else if' which are not valid in Go.

Using 'elif' which is from other languages.

In Go, the correct keyword for the alternative block is else, not elseif or others.

4fill in blank

hard

Complete the code to check if a number is negative or zero and print the correct message.

Go

package main
import "fmt"
func main() {
    num := -3
    if num {BLANK_1}} 0 { {
        fmt.Println("Negative or zero")
    } else {
        fmt.Println("Positive")
    }
}

D>

💡 Hint

Common Mistakes

Using '==' instead of '<=' for the condition.

Forgetting the opening brace '{' after the condition.

The condition num <= 0 checks if the number is negative or zero. The opening brace { starts the block.

5fill in blank

hard

Fill all three blanks to create a nested if–else that prints "Positive even", "Positive odd", or "Non-positive".

Go

package main
import "fmt"
func main() {
    num := 8
    if num [1] 0 {
        if num [2] 2 [3] 0 {
            fmt.Println("Positive even")
        } else {
            fmt.Println("Positive odd")
        }
    } else {
        fmt.Println("Non-positive")
    }
}

💡 Hint

Common Mistakes

Using '<' instead of '>' for positive check.

Using '=' instead of '==' for comparison.

Using '/' instead of '%' for remainder.

The outer if checks if num > 0. The inner if checks if num % 2 == 0 to find even numbers.
