顺序容器的添加/删除操作(会改变容器大小,array不支持这些操作) emplace操作构造函数而不是拷贝元素。 在调用emplace_back时,会在容器管理的内存空间中直接创建对象,而调用push_back则会创建一个局部临时对象,并将其压入容器中。 包括array在内的每个顺序容器都有一个front成员函数,而除forward_list之外的所有顺序容器...

那可以扔了,换<C++Pimer>或<C++程序设计语言>吧).看看,你类的有引用类型的数据成员,还记得引用必须在定义时初始化不?那么你定义构造函数(不是声明)就必须在初始化列表里初始化引用,改成如下就行了 TProgressDialog(std::ostream &_s = std::cout): s(_s) {};
