// 07枚举
package main
import (
"fmt"
)
func main() {
// 1.iota常量自动生成器，每个一行，自动累加1
// 2.iota给常量赋值使用
const (
a = iota // 0
b = iota // 1
c = iota // 2
)
fmt.Printf("a = %d,b = %d,c = %d\n", a, b, c)
// 3.iota遇到const,就会重置为0
const d = iota
fmt.Printf("d = Î%d\n", d)
// 4.可以只写一个iota,效果和上面一样
const (
a1 = iota // 0
b1
c1
)
fmt.Printf("a1 = %d,b1 = %d,c1 = %d\n", a1, b1, c1)
// 5.如果是同一行，值都一样
const (
i = iota
j1, j2, j3 = iota, iota, iota //同一行都是1
k = iota
)
fmt.Printf("i=%d,j1=%d,j2=%d,j3=%d,k=%d\n", i, j1, j2, j3, k)
}
