Augmented Assignment Operators

Part of the Fundamentals section of Coddy's GO journey — lesson 19 of 109.

Augmented assignment operators combine an arithmetic operation with assignment. They're shortcuts that make your code cleaner.

Instead of writing:

score := 100
score = score + 50

Use the += operator:

score := 100
score += 50
fmt.Println(score)

Output:

Other augmented operators include -=, *=, /=, and %=:

count := 10
count *= 5  // Same as: count = count * 5
fmt.Println(count)

Output:

Challenge

Beginner

In this challenge, you'll practice using augmented assignment operators in Go. Augmented assignment operators combine an arithmetic operation with assignment (like +=, -=, *=, /=, %=).

We have a variable score that starts at 10. Your task is to use augmented assignment to increase the score by 5.

Try it yourself

package main

import "fmt"

func main() {
	// Starting score
	score := 10
	
	// TODO: Use augmented assignment (+=) to increase score by 5
	
	// Print the final score
	fmt.Println("Final score:", score)
}
