Infinite loops in Go - Mini Project: Build & Apply

Infinite loops

📖 Scenario: Imagine you want to create a simple program that keeps printing a message forever, like a clock ticking every second. This helps understand how infinite loops work in programming.

🎯 Goal: Build a Go program that uses an infinite loop to print the message "Tick" repeatedly.

📋 What You'll Learn

Create a variable to hold the message string

Use an infinite for loop to repeat the action

Print the message inside the loop

💡 Why This Matters

🌍 Real World

Infinite loops are used in programs that need to keep running, like servers or clocks.

💼 Career

Understanding infinite loops helps in writing programs that wait for events or run continuously without stopping.

1

DATA SETUP: Create a message variable

Create a variable called message and set it to the string "Tick".

Go

// Your code here

Need a hint?

Use message := "Tick" to create the variable.

2

CONFIGURATION: Prepare for the infinite loop

Keep the variable message and add an infinite for loop below it.

Go

package main

import "fmt"

func main() {
    message := "Tick"
    // Add an infinite for loop below
}

Need a hint?

Use for { to start an infinite loop in Go.

3

CORE LOGIC: Print the message inside the infinite loop

Inside the infinite for loop, use fmt.Println(message) to print the message repeatedly.

Go

package main

import "fmt"

func main() {
    message := "Tick"
    for {
        // Print the message here
    }
}

Need a hint?

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

4

OUTPUT: Run the program to see the infinite output

Run the program. It should print Tick repeatedly without stopping.

Go

package main

import "fmt"

func main() {
    message := "Tick"
    for {
        fmt.Println(message)
    }
}

// Run the program to see the output

Need a hint?

The program will print Tick many times. You can stop it manually.
