(Go)05.基本数据类型和操作符

保留的关键字段

1.Question1

package main


import (
    "fmt"
)

func list(n int) {

    for i := 0; i <= n; i++ {
        fmt.Printf("%d+%d=%d
", i, n - i, n)
    } 
}

func main() {
    list(10)
}

2.Question2

代码目录结构

package add


var Name string = "hello world"
var Age int = 20

package main


import (
    "go_dev/day2/example2/add"
    "fmt"
)


func main() {

    fmt.Println("Name =", add.Name)
    fmt.Println("age =", add.Age)
}

验证结果必须以大写字母开头

3.Question3

package main

import (
    "time"
    "fmt"
)


const (
    Female = 2
    Man =1
)

func main() {
    for {
    second := time.Now().Unix()
    if (second % Female ==0) {
        fmt.Println("Female")
    } else {
        fmt.Println("Man")
    }
    time.Sleep(1000 * time.Millisecond)
    }
}

#Millisecond 毫秒
