Sales_data& operator+=(const Sales_data&); } 输入和输出运算符 IO标准库分别使用>>和<<执行输入和输出操作。对于两个运算符来说,IO库定义了用其读写内置类型的版本,而类则需要自定义适合其对象的新版本以支持IO操作 重载输出运算符<< 通常情况下,输出运算符的第一个形参是一个非常量ostream对象的引用。
operator bool()const { return IsValid();} 这也就是以为着允许ScopePtr类型转换为bool类型,是添加了一种隐式转换的规则,如果你查看unique_ptr的定义就会发现其中也有 explicit operator bool() const noexcept { return get() != nullptr; } 注意 需要注意的是,这样的语法因为是为了隐式转换,所以会带来语...
