Golang | Iota
“Learn how to utilize the iota identifier in Golang through a basic example. Iota is a special identifier in Golang that simplifies the declaration of sequential integer constants. In this short video, we explore two cases demonstrating the usage of iota. Watch to grasp how iota facilitates the definition of constant values in Golang code.”

// Basic Example
// const (
// A = 0 // First = 0
// B = 1 // Second = 1
// C = 2 // Third = 2
// )
//case 1:
const (
A = iota // First = 0
B = iota // Second = 1
C = iota // Third = 2
)
//case 2:
const (
First = iota // First = 0
Second // Second = 1
Third // Third = 2
)
func main() {
GoIota()
}
func GoIota() {
fmt.Println(A, B, C)
fmt.Println(First, Second, Third)
}
