Go Operators
Go Operators
Operators are used to perform operations on variables and values.
The + operator adds together two values, like in the example below:
Example
package main
import ("fmt")
func main() {
var a = 15 + 25
fmt.Println(a)
}

Although the + operator is often used to add together two values, it can also be used to add together a variable and a value, or a variable and another variable:
Example
package main
import ("fmt")
func main() {
var (
sum1 = 100 + 50 // 150 (100 + 50)
sum2 = sum1 + 250 // 400 (150 + 250)
sum3 = sum2 + sum2 // 800 (400 + 400)
)
fmt.Println(sum3)
}
