If we need to interpolate a string, without printing it, then we can use fmt.Sprintf().

Just like fmt.Printf(), fmt.Sprintf() can also use verbs:

correctAns := "A"
answer := fmt.Sprintf("And the correct answer is… %v!", correctAns)

fmt.Print(answer) // Prints: And the correct answer is… A!

fmt.Sprintf() works very similarly to fmt.Printf(), the major difference is that fmt.Sprintf() returns its value instead of printing it out!
