In this program, we will use strings.Repeat() function by specified number of times Repeats the specified string and prints the results on the console screen.

// strings.Repeat() function

package main

import "fmt"
import "strings"

func main() {
    var str string = "India "
    var result string

    result = strings.Repeat(str, 4)

    fmt.Println("String After repetition:", result)
}

Explanation:

• In the above program, we declared the package main. The main package is used to tell the Go language compiler that this package must be compiled and generate an executable file. Here we have imported the fmt package which contains the fmt package files and then we can use the functions related to the fmt package.

• In the main() function, we created two variables str and result. Then we use the strings.Repeat() function to repeat the specified string 4 times and assign it to the result variable. After that, we print the results on the console screen.

Example 2: Repeat the string 0 times

// Golang program to demonstrate the
// strings.Repeat() function

package main

import "fmt"
import "strings"

func main() {
    var str string = "India "
    var result string

    result = strings.Repeat(str, 0)

    fmt.Println("String After repetition:", result)
}
