Go语言实现猜数字游戏

Posted 2022-05-10 做1个快乐的程序员

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('\\n') //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, "\\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")
			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
