Golang examples - Program to add/sum of two numbers or integers


In this program,Ā  we have two programs to add two numbers. The First program, We will store the numbers and the addition of two numbers. The second program, take the two numbers from the user and return the sum of two numbers.

Example: Sum of two numbersĀ 

In this program, variables are declared and did inline assignment statements. This is one way of declaring multiple variables of the same type in golang
The same way can be rewritten using short assignment operator as below n1, n2, result := 10, 3, 0 .
The variable types can be inferred from right hand values

package main  
  
import (  
 "fmt"  
)  
  
func main() {  
 var n1, n2, result = 10, 3, 0 // Declare variable and assign values  
 result = n1 + n2  
 fmt.Println("Sum of two numbers: ", result)  
  
}  

Output is

Sum of two numbers:  13 

ScanlnĀ function example -Sum numbers taken input from the standard consoleĀ Ā 

Ā In this program, numbers are taken from the standard console. Scanln function is used to stop the control until user is entered the number And sum of this two numbers are returned to console

package main  
  
import (  
 "fmt"  
)  
  
func main() {  
 fmt.Print("Please enter first number: ")  
 var n1 int  
 fmt.Scanln(&n1) // take input from user  
 fmt.Print("Please enter Second number: ")  
 var n2 int  
 fmt.Scanln(&n2) // take input from user  
 result := n1 + n2  
 fmt.Println("Sum of two numbers: ", result)
