package main import "fmt" func main() { //1、iota常量自动生成器 每隔一行 自动累加1 //2、iota给常量赋值 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 = %d\n", d) //可以只写一个iota const ( a1 = iota //0 b1 //1 c1 //2 ) fmt.Printf("a1 = %d,b1 = %d,c1 = %d\n", a1, b1, c1) //5 如果在同一行 值都一样 const ( i = iota j1, j2, j3 = iota, iota, iota k = iota ) fmt.Printf("i = %d,j1 = %d,j2 = %d,j3 = %d\n,k = %d\n", i, j1, j2, j3, k) }
