For my project, the role of the Lecturer (defined as a class) is to offer projects to students. Project itself is also a class. I have some global dictionaries, keyed by the unique numeric id's for lecturers and projects that map to objects. Thus for the "lecturers" dictionary (currently): lecturer[id] = Lecturer(lec_name, lec_id, ma...
I've been struggling with understanding how C++ classes include other classes. I'm guessing this is easier to understand without any preconceived notions. Assume my two classes are Library and Book. I have a .h and .cpp file for each. My "main.cpp" runs a simple console app to use them. Here is a simple example: //Library.h #ifn...

The instance of TPetList is displayed in a TListView component using a for loop. TPet is based on TObject and has the following fields: city age breed Now I have a list of checkboxes where the user...
ArrayList array = new ArrayList(); Iterator it1 = array.iterator(); while (it1.hasNext()){ Myclass temp = it1.myGetterMethod(); System.out.println (temp); } This is what I would like to implement, but Iterator only returns a generic Object. When I call Object.getClass(), the class is Myclass. Does this mean that the Iterator is ...
Trying to create a base class from which I can derive different types. What's wrong with the following? class (Eq a) => MyClass a data Alpha = Alpha instance MyClass Alpha where Alpha == Alpha = True I get the error: test.hs:5:10: `==' is not a (visible) method of class `MyClass' Failed, modules loaded: none. ...
If I had: class A(object): varA = 1 inst = A() Then how would I retrieve the keys of all variables on inst? I'd want something like ["varA"] So far, I've gotten this: vars(inst.__class__).keys() #returns ['__dict__', '__weakref__', '__module__', 'varA', '__doc__'] I'm fine with that, I'd just ignore the double-under vars. My ...

I thought that constructors control initialization and operator= functions control assignment in C++. So why does this code work? #include <iostream> #include <cmath> using namespace std; class Deg { public: Deg() {} Deg(int a) : d(a) {} void operator()(double a) { cout << pow(a,d...
In Python, which is the best way (style wise) to allow public access to an object's variables? There are lots of options I've seen from different languages, I was wondering which of these (if any) is the preferred Python method? These are the options I'm currently torn between: Allow direct access to object variables (e.g. print(objec...
I have created a PHP class called formChecker.php. It validates a form. As a Java programmer, I would like to stick with the idea of creating an instance of this class in another class and run it from there. It doesn't seem to be working for me.The following is a demonstration: class formChecker{ ..... validation functions go here }...
