类派生列表以一个或多个基类命名,形式如下: class derived-class: access-specifier base-class 其中,访问修饰符 access-specifier 是 public...、protected 或 private 其中的一个,base-class 是之前定义过的某个类的名称。
optional.If True, then the newly created array will use the sub-class type of ‘a’, otherwise it will be a base-class
True, then sub-classes will be passed-through, otherwise the returned array will be forced to be a base-class
//派生类创建格式: class derived-class : access-specifier base-class /* ①access-specifier表示继承类型。...②base-class表示已有基类 */ ?
第三行,是个要注意的点,泛型约束要定义在类继承语法的后面,这是必要的,因为放在where后会引起歧义 约束类型有以下几个: struct T必须是值类型 class T必须是引用类型 base-class
类派生列表以一个或多个基类命名,形式如下: class derived-class: access-specifier base-class access-specifier:访问修饰符,与类的访问修饰限定符一样...,可以使用public、 protected 或 private,若未使用,默认为private; base-class:已经定义的某个类的名称; 下面对比下3种访问修饰符: 1)公有继承(public
