Hi all,
I have a very basic fundamental wuestion to ask. I am confused about
the difference between type and class? is "int","float"," double" a
type? With so many C++ gurus out here, I dont know whether should I
ask this question here or not? But if anyone can help me out, I'll feel
good.

Yes, these are built-in types, but they are not classes.
A class is also a type, but a type isn't necessarily a class.

ask this question here or not?
It's a completely valid question here.
But if anyone can help me out, I'll
feel good.
Good.

Nope, classes are just structs with a different default access level.
In truth, structs are classes as far as format C++ terms go. Either
one can have methods, neither is required to have (user-declared)
methods.
The following article should help:

I have been programming in C++ for over 4 years. I *think* I knew that
a struct could have a constructor but I decided to dig into it a little
more today, and found that there is very little difference between a
struct and a class in C++. Both have inheritance, access modifiers,
etc. The only diff I see is the default access level is public vs.
private.
I have always just used structs as a minimal class, as that is the way

In Access (2003) VBA, what is the difference between a Module and a
Class Module in the VBA development environment?
If I remember correctly, new types of objects (classes) can only be
defined in Class modules.

Hi,
i'm learning working with classes.
In class "classbase1", i defined an overridable function. In the class
"subclass1", i defined the same function with 'Overrides'.
In class "classbase2", i defined the same function and in the class
"subclass2", i defined the same function with 'Overloads'.
Result: i get the same output.

Hi,
I read the book C++ Primer, Fourth Edition By Stanley B. Lippman,
Jos¨¦e Lajoie, Barbara E. Moo
"If we define a class using the class keyword, then any members
defined before the first access label are implicitly private; ifwe
usethe struct keyword, then those members are public. Whether we define
a class using the class keyword or the struct keyword affects only the
default initial access level."
Now I defined a struct with...

Hello,
I understand the default-initialization happens if we don't initialize
an object explicitly. I think for an object of a class type, the
value is determined by the constructor, and for the built-in types,
the value is usually garbage. Is this right?
However, I'm a bit confused about value-initialization, when does it
happen, and what kind of values are assigned to objects?

I am learning C++ and I have been told that an object can be

Hello,
Can someone explain to me the difference between a type and a class?
After reading http://www.cafepy.com/article/python_types_and_objects/
it seems to me that classes and types are actually the same thing:
- both are instances of a metaclass, and the same metaclass ('type')
can instantiate both classes and types.
- both can be instantiated and yield an "ordinary" object
- I can even inherit from a type and get a class

For most users, this new feature is actually very convenient. If you want to control the update process,...
