Continue statement in Go - Mini Project: Build & Apply

Using the Continue Statement in Go

📖 Scenario: Imagine you are checking a list of daily temperatures to find which days were warm enough to go outside. You want to skip cold days and only note the warm days.

🎯 Goal: You will write a Go program that uses the continue statement inside a loop to skip cold days and print only the warm days.

📋 What You'll Learn

Create a slice of integers called temperatures with the exact values: 15, 22, 8, 19, 30, 12

Create an integer variable called warmThreshold and set it to 20

Use a for loop with the variable temp to go through temperatures

Inside the loop, use continue to skip temperatures less than warmThreshold

Print each warm temperature using fmt.Println(temp)

💡 Why This Matters

🌍 Real World

Filtering data based on conditions is common in many programs, like showing only important messages or selecting items that meet certain criteria.

💼 Career

Understanding how to use loops and control statements like <code>continue</code> helps you write efficient code that processes data correctly, a skill needed in software development.

1

Create the temperatures slice

Create a slice of integers called temperatures with these exact values: 15, 22, 8, 19, 30, 12

Go

// Create the temperatures slice with the exact values
// Your code here

Need a hint?

Use temperatures := []int{...} to create the slice with the exact numbers.

2

Add the warmThreshold variable

Create an integer variable called warmThreshold and set it to 20

Go

package main

func main() {
    temperatures := []int{15, 22, 8, 19, 30, 12}
    // Create warmThreshold variable and set it to 20
    // Your code here
}

Need a hint?

Use warmThreshold := 20 to create the variable.

3

Use a for loop with continue to skip cold days

Use a for loop with the variable temp to go through temperatures. Inside the loop, use continue to skip temperatures less than warmThreshold

Go

package main

func main() {
    temperatures := []int{15, 22, 8, 19, 30, 12}
    warmThreshold := 20

    // Loop through temperatures and skip cold days
    // Your code here
}

Need a hint?

Use for _, temp := range temperatures to loop. Use if temp < warmThreshold { continue } to skip cold days.

4

Print the warm temperatures

Inside the loop, after the continue statement, print each warm temperature using fmt.Println(temp)

Go

package main

import "fmt"

func main() {
    temperatures := []int{15, 22, 8, 19, 30, 12}
    warmThreshold := 20

    for _, temp := range temperatures {
        if temp < warmThreshold {
            continue
        }
        // Print the warm temperature
        // Your code here
    }
}

Need a hint?

Use fmt.Println(temp) to print the warm temperatures inside the loop.
