import "fmt" type Rank int const ( Rank001 Rank = iota Rank002 Rank003 Rank004 ) var rewards = [...]string{ "奖励1","奖励2","奖励3","奖励4", } func (r Rank) getReward() string { return rewards[r] } func main() { fmt.Println(Rank003.getReward()) }
通过这样的方式,灵活的将排名与奖励对应,并且“面向对象”,将排名,这个int类型声明为排名,并为其添加成员函数。常规方式在C/C++,Java中,就直接通过2个以维数组惊醒处理,但相对而言,go语言这种方式,真的很赞!
go time/time.go 中:
108 type Weekday int 109 110 const ( 111 Sunday Weekday = iota 112 Monday 113 Tuesday 114 Wednesday 115 Thursday 116 Friday 117 Saturday 118 ) 119 120 var days = [...]string{ 121 "Sunday", 122 "Monday", 123 "Tuesday", 124 "Wednesday", 125 "Thursday", 126 "Friday", 127 "Saturday", 128 } 129 130 // String returns the English name of the day ("Sunday", "Monday", ...). 131 func (d Weekday) String() string { return days[d] }
