Problem Solution:

In this program, we will find the average of three numbers and print the result on the console screen.

Program/Source Code:

The source code to find the average of three numbers is given below. The given program is compiled and executed successfully.

// Golang program to find the average of three numbers.

package main
import "fmt"

func main() {
    //Declare 4 integer type variables
    var num1 int =10
    var num2 int =20
    var num3 int =30
    var avg int=0 

    avg=(num1+num2+num3)/3
    
    fmt.Println("Average is: ",avg)
}

Output:

Average is:  20

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.

Now, we come to the main() function. The main() function is the entry point for the program. Here, we declared four variables num1, num2, num3, avg that are initialized with 10, 20, 30, 0 respectively.

avg = (num1+num2+num3)/3

In the above statement, we find the average of num1, num2, num3 variables and assigned the result to the avg variable. After that, we printed the result using Println() function on the console screen.
