class

问题 I'm new to classes and stuff like that.

问题 I am trying to store either the objects of a base class ( employee ), or pointers to the objects inside a vector/array in another class ( finance ) object. The number of employee objects depends on the user, so it needs to work dynamically. So far I have this: finance.h #ifndef FINANCE #define FINANCE #include "freight.h" class finance { public: finance(); ~finance(); }; #endif // FINANCE finance.cpp #include "finance.h" using namespace std; finance::finance() { vector<employee *> vemployee;

问题 So I'm using a CSS Image Hover Effect on my Wordpress website that works completely fine in Chrome, however it does not work at all in Firefox or Opera (nothing happens when I mouseover my image in those browsers). I've read about possible problems and could it be a conflict with the div class? I'm not sure. Here's the CSS: ::-moz-selection { background-color: #888; color: #fff; } ::selection { background-color: #888; color: #fff; } /*B&W*/ .bw { -webkit-transition: all .5s ease; -moz

问题 i am having a function which should be run only once for all instance of the class.i thought to use the static function calling method. all the web example shows that static function define in the Header file(inside the class) itself. my function is big one i cant define that in header file what should i do? for that. 回答1: Like you do for normal functions: FooBar.h #ifndef FOOBAR_H #define FOOBAR_H class FooBar { public: static void test(); }; #endif FooBar.cpp #include "FooBar.h" void FooBar

问题 When I read Python Cookbook 3Edition recipe 9.18, I run into a class definition with parent Class and some optional argument, when I look it up, I know that python 3.6 add a new feature __init_subclass__() method for parent class, but the book is written based on Python3.3, so what method will take these arguments other than a metaclass the class definition is here: class Spam(Base, debug=True, typecheck=False): ...

问题 I normally use nested dictionaries, but I'd like to move into classes and objects. I have a list of home work grades that look like: assignment_name assignment_subject student_name due_date grade grade_pct rank I'd like to make an object that holds all the students and each students holds all of their assignments details.
