Вот как можно определить эту процедуру.
这是定义它的一种方法
Назовем входные значения a и b,
我们将输入取名为 a 和 b
и все, что нам нужно будет сделать, – это получить строку-сцепку входных значений.
我们需要做的是生成一个字符串 将 a 和 b 连接起来
Мы можем сделать это с помощью единственной команды return.
我们可以通过一个返回语句来达成目的
В ней мы вернем результат, равный a + b + b + a.
我们将会把 a+b+b+a 作为结果
Теперь убедимся, что она работает, передав в нее значения 'a' и 'b'.
现在 让我们测试一下它是否可以运作 传入 a 和 b
Запустим код и получим результат 'abba'.
运行函数 然后得到结果：'abba'
Мы можем попробовать еще один пример, передав значения 'dog' и 'cat'
我们可以尝试其他的例子 传入 'dog' 和 'cat'
и получив 'dogcatcatdog'.
现在我们得到 'dogcatcatdog'
Пока что все создаваемые нами процедуры были довольно простыми.
到目前为止 我们定义的所有函数都非常简单
Они требовали одной, максимум двух строк кода.
它们只要求1行 或2行代码
В последнем задании этого подраздела, мы зададим гораздо более сложный вопрос.
作为这部分的最后一个练习 我们将会问一个更加富有挑战性的问题
