Recap - Variables and Types

Part of the Fundamentals section of Coddy's GO journey — lesson 14 of 109.

Challenge

Easy

In this challenge, you'll practice working with different variable types in Go and printing them to the console.

You need to:

Define a new integer variable named 'quantity' with value 5
Print the product name with a label
Print the quantity with a label

Make sure to use the variables in your print statements rather than hardcoding values where possible.

Expected output format:

Product: Coffee Mug
Quantity: 5

Try it yourself

package main

import "fmt"

func main() {
  // Define given variables
  productName := "Coffee Mug"
  
  // TODO: Define a new integer variable named 'quantity' with value 5
  
  // TODO: Print the product name with a label: "Product: Coffee Mug"
  
  // TODO: Print the quantity with a label: "Quantity: 5"
}
