stack.go

package stack

type Stack struct{
    i        int
    data  [10]int
}

func (S *Stack) Push(n int) {
    S.data[S.i] = n
    S.i++
}

demothree.go

package main

import(
"fmt"
"stack"
)

func main() {
    var s stack.Stack
    fmt.Println(s)
    stack.Push(8)
    fmt.Println(s)
}

執(zhí)行結果為：

λ go run demothree.go
# command-line-arguments
.\demothree.go:11:2: undefined: stack.Push

看著教程書的答案寫的，仍是很是苦惱。。
