Overview

Sprintf function of fmt package can be used to format the string without printing it.  It is similar to Printf function with the only difference between the two being

• Printf formats and print the message
• Sprintf only formats the message.

Below is the syntax of the Sprintf function

func Sprintf(format string, a ...interface{}) string

The Sprintf function formats the string according to format specifier and returns the resultant string

Example

Let’s see a program for this

package main

import "fmt"

func main() {
    formattedMessage := fmt.Sprintf("Name is: %s. Age is: %d", "John", 21)
    fmt.Println(formattedMessage)
}

Output

Name is: John. Age is: 21

In the above program fmt.Sprintf correctly formats the message while fmt.Println is used to print the formatted message
