- Python 示例
python
import random
def guess_number(): ns66.cn
number_to_guess = random.randint(1, 100)
guess = None
attempts = 0
print("欢迎来到猜数字游戏！我已经想好了一个1到100之间的数字。")
while guess != number_to_guess:
try:
guess = int(input("请输入你猜的数字："))
attempts += 1
if guess < number_to_guess:
print("太小了！")
elif guess > number_to_guess:
print("太大了！")
else:
print(f"恭喜你！答对了。你总共猜了{attempts}次。")
except ValueError:
print("请输入一个有效的数字！")
guess_number()
2. JavaScript 示例 (在浏览器控制台运行)
javascript
function guessNumber() {
let numberToGuess = Math.floor(Math.random() * 100) + 1;
let guess = null;
let attempts = 0;
console.log("欢迎来到猜数字游戏！我已经想好了一个1到100之间的数字。");
while (guess !== numberToGuess) {
guess = parseInt(prompt("请输入你猜的数字："), 10);
attempts++;
if (isNaN(guess)) {
console.log("请输入一个有效的数字！");
continue;
}
if (guess < numberToGuess) {
console.log("太小了！");
} else if (guess > numberToGuess) {
console.log("太大了！");
} else {
console.log(`恭喜你！答对了。你总共猜了${attempts}次。`);
}
}
}
guessNumber();
3. Java 示例 (简单控制台应用)
java
import java.util.Random;
import java.util.Scanner;
public class GuessNumberGame {
public static void main(String[] args) {
Random rand = new Random();
int numberToGuess = rand.nextInt(100) + 1;
Scanner scanner = new Scanner(System.in);
int guess = 0;
int attempts = 0;
System.out.println("欢迎来到猜数字游戏！我已经想好了一个1到100之间的数字。");
while (guess != numberToGuess) {
System.out.print("请输入你猜的数字：");
if (scanner.hasNextInt()) {
guess = scanner.nextInt();
attempts++;
if (guess < numberToGuess) {
System.out.println("太小了！");
} else if (guess > numberToGuess) {
System.out.println("太大了！");
} else {
System.out.println("恭喜你！答对了。你总共猜了" + attempts + "次。");
}
} else {
System.out.println("请输入一个有效的数字！");
scanner.next(); // 清除无效输入
}
}
scanner.close();
}
}
以上三个示例分别展示了如何在Python、JavaScript（在浏览器环境）和Java（控制台应用）中实现一个简单的猜数字游戏。每种语言都有其独特的语法和库，但基本逻辑是相似的。由于篇幅限制，我会以三种流行的编程语言为例，来展示一个简单的猜数字游戏的基本实现。这个游戏将随机生成一个1到100之间的数字，玩家需要猜测这个数字是多少，直到猜对为止。
