+# 教程
+
+通过实际示例学习 Oraset 编程语言 B-5 版本，从基础输出到循环和条件判断。
+
+## 示例 1：基本输出
+
+```oraset
+// hello.ora
+print("Welcome to Oraset B-5!");
+print("This is my first program.");
+```
+
+输出：
+
+```
+Welcome to Oraset B-5!
+This is my first program.
+```
+
+## 示例 2：变量和计算
+
+```oraset
+// calc.ora
+var a = 10;
+var b = 20;
+var sum = a + b;
+print("The sum is:", sum);
+```
+
+输出：
+
+```
+The sum is: 30
+```
+
+## 示例 3：条件判断
+
+```oraset
+// grade.ora
+var score = 85;
+if (score >= 60) {
+    print("Pass!");
+} else {
+    print("Fail!");
+}
+```
+
+输出：
+
+```
+Pass!
+```
+
+## 示例 4：循环
+
+```oraset
+// loop.ora
+var i = 1;
+while (i <= 5) {
+    print("Count:", i);
+    i++;
+}
+```
+
+输出：
+
+```
+Count: 1
+Count: 2
+Count: 3
+Count: 4
+Count: 5
+```
+
+## 示例 5：不换行输出
+
+```oraset
+// inline.ora
+print("Loading", "nel");
+print(".");
+print(".");
+print(" Done!");
+```
+
+输出：
+
+```
+Loading...
+ Done!
+```
+
+## 示例 6：文件级配置
+
+```oraset
+// no_newline.ora
+sg<nel>
+print("All");
+print("on");
+print("same");
+print("line");
+```
+
+输出：
+
+```
+Allonsameline
+```
+
+## 示例 7：数组
+
+```oraset
+// array.ora
+var arr = [10, 20, 30, 40, 50];
+print("Array:", arr);
+print("First element:", arr[0]);
+print("Array length:", arrlen(arr));
+
+arr[2] = 35;
+print("Modified array:", arr);
+```
+
+输出：
+
+```
+Array: [10, 20, 30, 40, 50]
+First element: 10
+Array length: 5
+Modified array: [10, 20, 35, 40, 50]
+```
+
+## 示例 8：复合赋值
+
+```oraset
+// compound.ora
+var x = 10;
+x += 5;
+print("x += 5:", x);
+x *= 2;
+print("x *= 2:", x);
+x -= 3;
+print("x -= 3:", x);
+```
+
+输出：
+
+```
+x += 5: 15
+x *= 2: 30
+x -= 3: 27
+```
+
+## 示例 9：函数
+
+```oraset
+// function.ora
+function add(a, b) {
+    return a + b;
+}
+
+function multiply(a, b) {
+    return a * b;
+}
+
+var result = add(5, 3);
+print("5 + 3 =", result);
+
+result = multiply(4, 6);
+print("4 * 6 =", result);
+```
+
+输出：
+
+```
+5 + 3 = 8
+4 * 6 = 24
+```
+
+## 示例 10：数学函数
+
+```oraset
+// math.ora
+var pi = 3.14159;
+print("sin(pi/2) =", sin(pi/2));
+print("sqrt(16) =", sqrt(16));
+print("abs(-42) =", abs(-42));
+print("pow(2, 8) =", pow(2, 8));
+print("rand() =", rand());
+```
+
+输出：
+
+```
+sin(pi/2) = 1
+sqrt(16) = 4
+abs(-42) = 42
+pow(2, 8) = 256
+rand() = 0.123456
+```
+
