For loop basics in Go - Mini Project: Build & Apply

For loop basics

📖 Scenario: You work in a small grocery store. You have a list of fruit names that you want to check one by one.

🎯 Goal: You will write a Go program that uses a for loop to go through a list of fruits and print each fruit's name.

📋 What You'll Learn

Create a slice of strings with exact fruit names

Create a variable to count fruits

Use a for loop with index and value to iterate over the slice

Print each fruit name inside the loop

Print the total number of fruits after the loop

💡 Why This Matters

🌍 Real World

Loops are used to process lists of items like products, names, or data entries one by one.

💼 Career

Understanding loops is essential for any programming job because they help automate repetitive tasks efficiently.

1

Create a slice of fruits

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

Go

package main

func main() {
    // Create the slice fruits here
    // Your code here
}

Need a hint?

Use fruits := []string{...} to create the slice with the exact fruit names.

2

Create a counter variable

Create an integer variable called count and set it to 0 to count the fruits.

Go

package main

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

Need a hint?

Use count := 0 to create the counter variable.

3

Use a for loop to print fruits

Use a for loop with variables index and fruit to iterate over fruits. Inside the loop, print the fruit name using fmt.Println(fruit) and increase count by 1.

Go

package main

import "fmt"

func main() {
    fruits := []string{"apple", "banana", "cherry", "date", "elderberry"}
    count := 0
    // Write for loop here
    // Your code here
}

Need a hint?

Use for index, fruit := range fruits to loop. Use fmt.Println(fruit) to print each fruit. Increase count by 1 inside the loop.

4

Print the total count

After the loop, print the total number of fruits using fmt.Println("Total fruits:", count).

Go

package main

import "fmt"

func main() {
    fruits := []string{"apple", "banana", "cherry", "date", "elderberry"}
    count := 0
    for index, fruit := range fruits {
        fmt.Println(fruit)
        count++
    }
    // Print total count here
    // Your code here
}

Need a hint?

Use fmt.Println("Total fruits:", count) to show the total number of fruits after the loop.
