Re: [Dev-C++] memory allocation

[Daniel G. <sp...@ho...>]

umm are we talking about the dynamic memory allocation using pointers and 
the new / delete operators?

class MyClass; // forward declaration

MyClass* Ptr = new MyClass; // Ptr points to an object of type MyClass, 
created dynamically.

no it must be the same, because you are creating a new instance of a class. 
You'll get yClass1 undefined otherwise.

Hi,

In your example I think the name you give to new must be different than 
class name.

such as:

class MyClass;
MyClass* Ptr = new MyClass1;

Actually, it's the little guy between the star and the equal (now called
Ptr) that have to have a different name than the class name.

After new, you HAVE to specify the name of an existing data type, or new
wouldn't know what kind of object to allocate.
