go练习:交叉输出数字和字母

package main

import (
    "fmt"
)

func main() {
    var h = 65
    var c, d, e = make(chan int), make(chan int), make(chan int)

    go func() {
        for i := 0; i < 26; i++ {
            <-c
            fmt.Print(i+1, ">")
            d <- 1
        }
    }()
    go func() {
        for i := h; i < h+26; i++ {
            <-d
            fmt.Printf("%c|", i)
            if i < h+26-1 {
                c <- 1
            }
        }
        e <- 1
    }()
    c <- 1
    <-e
}
