Switch Case Statement in Golang

PROGRAM:

package main

import "fmt"

func main() {
    /* type has to match with case, there is no need break like C++ or JAVA has*/
    pc1 := "ibm"
    switch pc1 {
    case "dell":
        fmt.Println("DELL Computer")
    case "ibm":
        fmt.Println("IBM Computer")
    case "hp":
        fmt.Println("HP Computer")
    default:
        fmt.Println("APPLE Computer")
    }

    /* initialisation int the same statement */
    switch pc2 := "hp"; pc2 {
    case "dell":
        fmt.Println("DELL Computer")
    case "ibm":
        fmt.Println("IBM Computer")
    case "hp":
        fmt.Println("HP Computer")
    default:
        fmt.Println("APPLE Computer")
    }

    /* fallthrough keyword helps to execute block below the case */
    switch pc3 := "ibm"; pc3 {
    case "dell":
        fmt.Println("DELL Computer")
    case "ibm":
        fmt.Print("IBM & ")
        fallthrough
    case "hp":
        fmt.Println("HP Computer")
    default:
        fmt.Println("APPLE Computer")
    }
} 

OUTPUT:
IBM Computer
HP Computer
IBM & HP Computer
