Hello, my question is this.
In C++, how do i call a method member of class A from a class B, using a pointer.
By the way Class A and B are of different types.

I read that when a pointer is pointing to member function it can only point member functions within the class. But how can i point to a member function outside the class.?????

for example

class A...

I am completely stuck and am looking for guidance. I am creating my own version of the sets class, making the class called Set. I have created a test function as well. Everything works great until I get to the union/subtract part.

Code:

def intersection(self,set2):
        self.inter=Set([])
        for i in self.elements:
            for j in set2.elements:
                if i == j:
                    self.inter

Overview

This article shows how to set up and use a Class Module, as well as, more specifically, how to open forms such that they appear as a hierachical menu structure. Form A opens Form B and, while Form B is still open, remains hidden from view. As and when Form B terminates, Form A comes back into view and reassumes the focus.

The code for classForm below includes examples of setting class properties as well as various...

Hi all,
I am a newbie in VB.Net and was kind of lost in programming using it compared to the old VB6.

In VB6 I was able to create, declare or assign values to global variables. But now, it seems that every variable should be included in some class (I'm not sure).

What I need to do is to have some global variables and use them to different web pages without using the classes. What I mean is I do not like to use...

I've started using class modules, and admittedly is quite inexperienced in this particular area, and there is one thing I can't seem to wrap my head around.

Part of the code is the property StartHeight. Get and Let shown below:

Code:

Public Property Let StartHeight(intValue As Integer)
    pIntStartHeight = intValue
End Property
Public Property Get StartHeight() As Integer
    StartHeight = pIntStartHeight

A simplified example of what I am looking for comes from a restaurant.

The Restaurant has 30 tables (Parent Class).
Each table has a server and location (Parent Properties).
At each table is an array of patrons (Child Class).
Each patron has name and alergies (Child Prop's).

I thought to set it up like this:

Code:

class patron {
  public Name;
  public Allergies;
}
class table {

I have a class called TopScores which contains two objects score and name. I need to sort them in descending order of score, but dont know how to do it :(

Here's the code

Code:

class TopScore():
  def __init__(self):
    self.Name = "-"
    self.Score = 0

Basically, it saves high scores for a game. The Name is a string and Score is an integer.

Hi,
I was just wondering how the new operator (in C++) knows how much memory to allocate when creating an object of a class such as shown below:

i.e

class Books
{

}

int main()
{
....
Books textbook = new Books();
....
}

I have a stronger C background and I know that in C we have to specify the memory size for...

I have a homework for tomorrow, and I simply can't solve it.
I have a list (with template) class, I wrote and it has an operator:
