系统随机生成一个数，通过输入数，系统判断输入的数正确与否

[生成随机数]

package main

import (
    "fmt" 
    "math/rand"
    )

func main(){
    maxnum := 100
    secretnumber := rand.Intn(maxnum)
    fmt.Println("The secret number is ", secretnumber)
}

[生成随机数V2]

package main
import (
    "fmt"
    "math/rand"
    "time"
)
func main {
maxNum := 100
rand.Seed(time.Now(.UnixNano()secretNumber := rand.Intn(maxNum)
fmt.Println("The secret number is ", secretNumber)
}

[读取用户输入]

package main
import (
    "bufio"
    "fmt"
    "math/rand"
    "os"
    "strconv"
    "strings"
    "time"
)

func main(){
maxNum := 100
rand.Seed(time.Now(.UnixNano()secretNumber := rand.Intn(maxNum)
fmt.Println("The secret number is ", secretNumber)

fmt.Println("Please input your guess")
reader := bufio.NewReader(os.Stdin)
input, err := reader.fteadString("\n')//读取一行输入
if err != nil {
    fmt.Println("An error occured while reading input. Please try again",err)
    return
 }
input = strings.TrimSuffix(input, "n")//去掉换行符

guess,err := strconv.Atoi(input)//转换成数字
if err != nil {
    fmt.Println("Invalid input. Please enter an integer value")
    return
 }
fmt.Println("You guess is",guess)

}
