Switch expression behavior in Go - Interactive Code Practice

Practice - 5 Tasks

1fill in blank

easy

Complete the code to print the correct message based on the value of x.

Go

package main
import "fmt"
func main() {
    x := 2
    switch x {
    case [1]:
        fmt.Println("Two")
    default:
        fmt.Println("Other")
    }
}

💡 Hint

Common Mistakes

Choosing a case value different from x causes the default case to run.

The switch checks the value of x. To print "Two", the case must match 2.

2fill in blank

medium

Complete the switch to print "Even" when n is 2 or 4.

Go

package main
import "fmt"
func main() {
    n := 4
    switch n {
    case 2, [1]:
        fmt.Println("Even")
    default:
        fmt.Println("Odd")
    }
}

💡 Hint

Common Mistakes

Adding odd numbers to the case list causes wrong output.

The switch case lists values that match n. To print "Even" for 2 and 4, include 4 in the case.

hard

Fix the error in the switch expression to correctly print "Hello" when s is "hi".

Go

package main
import "fmt"
func main() {
    s := "hi"
    switch [1] {
    case "hi":
        fmt.Println("Hello")
    default:
        fmt.Println("Bye")
    }
}

💡 Hint

Common Mistakes

Using a string literal or expression instead of the variable causes no matches.

The switch expression should be the variable s to compare its value to cases.

4fill in blank

hard

Fill both blanks to create a switch that prints "Small" for values less than 10 and "Large" otherwise.

Go

package main
import "fmt"
func main() {
    num := 7
    switch {
    case num [1] 10:
        fmt.Println("Small")
    default:
        fmt.Println("Large")
    }
}

💡 Hint

Common Mistakes

Using > or == causes wrong output.

In a switch without an expression, each case is a condition. To print "Small" when num is less than 10, use <.

5fill in blank

hard

Fill all three blanks to create a switch that prints the day type based on the day number (1-7).

Go

package main
import "fmt"
func main() {
    day := 6
    switch day {
    case [1], [2], [3]:
        fmt.Println("Weekend")
    default:
        fmt.Println("Weekday")
    }
}

💡 Hint

Common Mistakes

Including weekday numbers in the weekend case causes wrong output.

Days 6 and 7 are weekend days in this example. The switch case lists these days to print "Weekend".
