How to return multiple values from the function in Golang?

Problem Solution:

In this program, we will return multiple string values from a user-defined function to the calling function.

Program/Source Code:

The source code to return multiple values from a user-defined function is given below. The given program is compiled and executed successfully.

Golang code to demonstrate the example of returning the multiple values from the function

// Golang program to return multiple values
// from a user-defined function.

package main

import "fmt"

func RetMultipleValue() (string, string) {
	return "Hello ", "World"
}

func main() {
	val1, val2 := RetMultipleValue()
	fmt.Println(val1, val2)
}

Output:

Hello  World

Explanation:

In the above program, we declare the package main. The main package is used to tell the Go language compiler that the package must be compiled and produced the executable file. Here, we imported the fmt package that includes the files of package fmt then we can use a function related to the fmt package.

In this program, we created a user-defined function RetMultipleValue() to return two string values. which is given below.

func RetMultipleValue()(string,string){
    return "Hello ","World"
}

In the main() function, we called RetMultipleValue() function to return two string values "Hello " and "World", that are assigned to the variables val1 and val2 respectively.
