Go语言实现猜数字游戏

Go和C有很多语法相近，但是也有很大区别，像变量的命名以及很多标准库的引用，这里用Go语言实现了猜数字游戏。

package main

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

func main() {
          
   
	maxNum := 100
	rand.Seed(time.Now().UnixNano()) //用时间戳来初始化随机数种子
	secretNumber := rand.Intn(maxNum)
	fmt.Println("The secret number is ", secretNumber)

	fmt.Println("Please input your guess")
	reader := bufio.NewReader(os.Stdin)
	for {
          
   
		input, err := reader.ReadString(
) //读取一行输入
		if err != nil {
          
   
			fmt.Println("An error occured while reading input. Please try again", err)
			continue
		}
		input = strings.TrimSuffix(input, "
") //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")
			continue
		}
		fmt.Println("You guess is", guess)
		if guess > secretNumber {
          
   
			fmt.Println("Your guess is bigger than the secret number. Please try again")
		} else if guess < secretNumber {
          
   
			fmt.Println("Your guess is smaller than the secret number. Please try again")
		} else {
          
   
			fmt.Println("Correct, you Legend!")
			break
		}
	}
}
