📋 What You'll Learn

Create a string variable with a description of Go

Create a variable to hold the Go version

Combine the description and version into a message

Print the message to the console

💡 Why This Matters

🌍 Real World

Go is widely used for building fast and reliable software like web servers and tools.

💼 Career

Knowing how to write basic Go programs is essential for roles in backend development and cloud computing.

1

Create a description variable

Create a string variable called description and set it to the exact text: "Go is an open source programming language."

Go

# Your code here

Need a hint?

Use := to create and assign the variable in one step.

2

Add a Go version variable

Add a string variable called version and set it to the exact text: "1.20"

Go

package main

import "fmt"

func main() {
    description := "Go is an open source programming language."
    // Your code here
}

Need a hint?

Remember to use := to declare and assign the variable.

3

Combine description and version

Create a new string variable called message that combines description and version with a space and the text "version" in between. Use fmt.Sprintf to format it exactly as: "Go is an open source programming language. version 1.20"

Go

package main

import "fmt"

func main() {
    description := "Go is an open source programming language."
    version := "1.20"
    // Your code here
}

Need a hint?

Use fmt.Sprintf to create the formatted string.

4

Print the message

Use fmt.Println to print the message variable to the console.

Go

package main

import "fmt"

func main() {
    description := "Go is an open source programming language."
    version := "1.20"
    message := fmt.Sprintf("%s version %s", description, version)
    // Your code here
}

Need a hint?

Use fmt.Println(message) to print the message.
