Go Constant

Constants are used to represent fixed values; their values cannot be changed at a later stage in the program. Any attempt to change the value of a constant will cause a runtime panic. Constants are declared like variables, but with the const keyword, it can be character, string, boolean, or numeric values and cannot be declared using the := syntax.

Typed constants

In Golang, constants are typed when you explicitly specify the type in the declaration:

const CURRENT_YEAR int = 2022 

Untyped constants

In Golang, all constants are untyped unless they are explicitly given a type at declaration.

const CURRENT_YEAR = 2022 

The following is an example of using Go Constant:

package main
import "fmt"

const Pi = 3.14

func main() {
	fmt.Println("Value of Pi is ", Pi)


Value of Pi is 3.14
