 示例代码如下
 
+## 混有中文变量的猜数字游戏
 
 ```rust
-use std::io;
 use rand::Rng;
+use std::cmp::Ordering;
+use std::io;
 fn main() {
-    println!("Guass the number!");
-    println!("请输入出猜测的数字: ");
-    let mut guess = String::new();
     let 密码 = rand::thread_rng().gen_range(1..=100);
-    println!("密码是{}",密码);
-    let count = io::stdin()
-        .read_line(&mut guess)
-        .expect("failed to read line");
-    println!("你输入的是: {}", guess);
-    println!("你输入了{}个字符", count);
-    let x = 5;
-    let y = 10;
-    println!("x = {x} and y + 2 = {}", y + 2);
+    //println!("密码是{}", 密码);
+    loop {
+        println!("请输入出猜测的数字: ");
+        let mut guess = String::new();
+        let count = io::stdin().read_line(&mut guess).expect("读取输入失败!");
+        print!("你输入的是: {}", guess);
+        println!("你输入了{}个字符", count);
+        // 先判断是否输入 "exit" 或 "quit"
+        if guess.trim() == "exit" || guess.trim() == "quit" {
+            println!("退出游戏！");
+            break;
+        }
+        //数据类型转换
+        //数据类型判断，忽略非数字输入
+        let guess: u32 = match guess.trim().parse() {
+            Ok(num) => num,
+            //忽略非数字输入
+            Err(_) => continue,
+        };
+        match guess.cmp(&密码) {
+            Ordering::Less => println!("太小!"),
+            Ordering::Greater => println!("太大!"),
+            Ordering::Equal => {
+                println!("你赢了!");
