Switch statements

Go also supports a switch statement similar to that found in other languages such as, C or Java. The switch statement in Go achieves multi-way branching by evaluating values or expressions from case clauses, as shown in the following, abbreviated, source code:

import "fmt" 
 
type Curr struct { 
  Currency string 
  Name     string 
  Country  string 
  Number   int 
} 
 
var currencies = []Curr{ 
  Curr{"DZD", "Algerian Dinar", "Algeria", 12}, 
  Curr{"AUD", "Australian Dollar", "Australia", 36}, 
  Curr{"EUR", "Euro", "Belgium", 978}, 
  Curr{"CLP", "Chilean Peso", "Chile", 152}, 
  Curr{"EUR", "Euro", "Greece", 978}, 
  Curr{"HTG", "Gourde", "Haiti", 332}, 
  ... 
} 
 
func isDollar(curr Curr) bool { 
  var bool result 
  switch curr { 
  default: 
    result = false 
  case Curr...
