package main import "fmt" func main() { //create a map m := make(map[string]int) // assign value m["key1"] = 12 m["key2"] = 20 fmt.Println(m) // get value from map value1 := m["key1"] fmt.Printf("key1 : %d", value1) // get length of map fmt.Printf("\nLength : %d", len(m)) // get all key and value from map for key, value := range m { fmt.Printf("\n%s : %d", key, value) } // delete key from map delete(m, "key1") fmt.Println("\ncontent of map after deletion of 'key1'") for key, value := range m { fmt.Printf("%s : %d", key, value) } } |
