Accessing array elements in Go - Mini Project: Build & Apply

Accessing array elements

📖 Scenario: You are organizing a small fruit basket. You want to keep track of the fruits you have and check specific fruits by their position in the basket.

🎯 Goal: Learn how to create an array of fruits and access specific fruits by their position (index) in the array.

📋 What You'll Learn

Create an array of fruits with exact values

Create a variable to hold the index of the fruit to access

Access the fruit at the given index from the array

Print the accessed fruit

💡 Why This Matters

🌍 Real World

Arrays are used to store collections of items like fruits, names, or numbers where you want to access items by their position.

💼 Career

Understanding how to access array elements is fundamental for programming tasks such as data processing, user input handling, and working with lists in software development.

1

Create an array of fruits

Create an array called fruits with these exact values: "Apple", "Banana", "Cherry", "Date", "Elderberry".

Go

// Your code here

Hint

Use the syntax varName := [size]type{values} to create an array.

2

Create an index variable

Create an integer variable called index and set it to 2 to select the third fruit in the array.

Go

package main

func main() {
    fruits := [5]string{"Apple", "Banana", "Cherry", "Date", "Elderberry"}
    // Your code here
}

Hint

Use variableName := value to create and set a variable.

3

Access the fruit at the given index

Create a variable called selectedFruit and set it to the fruit at position index in the fruits array.

Go

package main

func main() {
    fruits := [5]string{"Apple", "Banana", "Cherry", "Date", "Elderberry"}
    index := 2
    // Your code here
}

Hint

Use arrayName[index] to access an element at a specific position.

4

Print the selected fruit

Use fmt.Println to print the value of selectedFruit.

Go

package main

import "fmt"

func main() {
    fruits := [5]string{"Apple", "Banana", "Cherry", "Date", "Elderberry"}
    index := 2
    selectedFruit := fruits[index]
    // Your code here
}

Hint

Use fmt.Println(variableName) to print the value to the screen.
