Problem Solution:

In this program, we will add two integer numbers and print addition on the console screen.

Program/Source Code:

The source code to add two integer numbers is given below. The given program is compiled and executed successfully.

//Golang program to add two integer numbers.

package main
import "fmt"

func main() {
    //Declare 3 integer type variables
    var num1 int =10
    var num2 int =20
    var num3 int =0
    
    //Add num1,num2 and assign result to num3
    num3=num1+num2
    
    fmt.Println("Addition is: ",num3)
}

Output:

Addition is:  30

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 three variables num1, num2, num3 that are initialized with 10, 20, 0 respectively.

num3 = num1 + num2

In the above statement, we added values of num1 and num2 and assigned the result into the num3 variable. After that, we printed the result using Println() function on the console screen.
