Appending to slices in Go - Mini Project: Build & Apply

Appending to slices

📖 Scenario: Imagine you are managing a list of fruits in a basket. You want to add more fruits to this basket as you go shopping.

🎯 Goal: You will create a slice of fruits, add more fruits to it using the append function, and then print the final list of fruits.

📋 What You'll Learn

Create a slice of strings called fruits with initial fruits

Create a slice of strings called newFruits with fruits to add

Use append to add newFruits to fruits

Print the final fruits slice

💡 Why This Matters

🌍 Real World

Managing lists of items dynamically is common in many programs, like shopping carts, playlists, or task lists.

💼 Career

Understanding slices and how to append to them is essential for Go developers working on data processing, web servers, or any application that handles collections of data.

1

Create the initial slice of fruits

Create a slice of strings called fruits with these exact values: "apple", "banana", "cherry".

Go

package main

import "fmt"

func main() {
    // Create the slice fruits with "apple", "banana", "cherry"
    // Your code here
}

Hint

Use fruits := []string{"apple", "banana", "cherry"} to create the slice.

2

Create a slice of new fruits to add

Create a slice of strings called newFruits with these exact values: "date", "elderberry".

Go

package main

import "fmt"

func main() {
    fruits := []string{"apple", "banana", "cherry"}
    // Create the slice newFruits with "date", "elderberry"
    // Your code here
}

Hint

Use newFruits := []string{"date", "elderberry"} to create the slice.

3

Append the new fruits to the original slice

Use the append function to add all elements of newFruits to fruits. Assign the result back to fruits.

Go

package main

import "fmt"

func main() {
    fruits := []string{"apple", "banana", "cherry"}
    newFruits := []string{"date", "elderberry"}
    // Append newFruits to fruits
    // Your code here
}

Hint

Use fruits = append(fruits, newFruits...) to add all new fruits.

4

Print the final fruits slice

Write a fmt.Println statement to print the fruits slice.

Go

package main

import "fmt"

func main() {
    fruits := []string{"apple", "banana", "cherry"}
    newFruits := []string{"date", "elderberry"}
    fruits = append(fruits, newFruits...)
    // Print the fruits slice
    // Your code here
}

Hint

Use fmt.Println(fruits) to display the slice.
