Untyped --  const  a ="abc"  Example for using Golang Constants: package main import "fmt" // declaring Multiple variables const ( a = 1 b = "hi" c = 1.1 ) func main() { fmt.Println(a) fmt.Println(b) fmt.Println(c) } Output: 1 hi 1.1 Another Example: package main import "fmt" func main() { const a = "Hello" a = "Hi" fmt.Println(a) } Output: ./prog.go:7:2: cannot assign to a (untyped string constant "Hello") Go build failed. Another Example: package main import "fmt" func main() { // declare and initialize a constant string const s string = "MY_CONST" // define a custom string type - str type str string // storing the const variable in a new variable is all...
