Nested conditional statements in Go - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to check if a number is positive.

Go

package main

import "fmt"

func main() {
    num := 5
    if num [1] 0 {
        fmt.Println("Positive number")
    }
}

💡 Hint

Common Mistakes

Using '<' instead of '>' will check for negative numbers.

Using '==' checks only if the number is zero.

The condition num > 0 checks if the number is positive.

2fill in blank

medium

Complete the code to check if a number is positive and even.

Go

package main

import "fmt"

func main() {
    num := 4
    if num > 0 {
        if num [1] 2 == 0 {
            fmt.Println("Positive even number")
        }
    }
}

💡 Hint

Common Mistakes

Using '/' divides the number but does not check for evenness.

Using '*' or '+' are arithmetic operations, not for checking divisibility.

The modulus operator % checks if the number is divisible by 2 (even).

3fill in blank

hard

Fix the error in the nested if statement to check if a number is negative and odd.

Go

package main

import "fmt"

func main() {
    num := -3
    if num [1] 0 {
        if num%2 != 0 {
            fmt.Println("Negative odd number")
        }
    }
}

💡 Hint

Common Mistakes

Using '>' checks for positive numbers instead of negative.

Using '==' checks if the number is zero.

The condition num < 0 checks if the number is negative.

4fill in blank

hard

Fill both blanks to check if a number is zero or positive and even.

Go

package main

import "fmt"

func main() {
    num := 0
    if num [1] 0 {
        if num [2] 2 == 0 {
            fmt.Println("Zero or positive even number")
        }
    }
}

💡 Hint

Common Mistakes

Using '>' excludes zero from the check.

Using '/' instead of '%' for checking evenness.

The first condition num >= 0 checks for zero or positive numbers.
The second condition num % 2 == 0 checks if the number is even.

5fill in blank

hard

Fill all three blanks to check if a number is negative, odd, and less than -10.

Go

package main

import "fmt"

func main() {
    num := -15
    if num [1] 0 {
        if num%2 [2] 0 {
            if num [3] -10 {
                fmt.Println("Negative odd number less than -10")
            }
        }
    }
}

💡 Hint

Common Mistakes

Using '==' instead of '!=' for odd check.

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

The first condition num < 0 checks negativity.
The second condition num % 2 != 0 checks oddness.
The third condition num <= -10 checks if the number is less than or equal to -10.
