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
