[Cpp-Programming] Re: doubt in c++

Hi,

square obj_sqr1;
- By this way, you can create an object at compile time i.e. when program gets compiled, memory is allocated for obj_sqr1. It's static allocation.

The other way is runtime/dynamic allocation/creation.

But I found this site which confused me too:
http://www.codeguru.com/forum/archive/index.php/t-250505.html

Now my question to group is: Is it true dynamic creation is not supported directly by the C++ language."

Niketa

hi,

i'm pretty new to c++. i have got a simple doubt. please answer.

i have a class called square.

class square
{
//some implementation here
}

now when i write the main program i create the object. here is where
i'm confused. i feel i can create the object square in two ways. let
me know if i'm correct.

square obj_sqr1; // this is one way

square* ptr_square;
ptr_square = new square ; //  using the new operator, forgive me if
the syntax is wrong

what is the difference between the two ? are they same ? ..
