Static Attribute in Class

[luckycusp]

class xyz
{
public: 
   static int abc;
}obj1,obj2;

Are static attributes allowed in a Class?

How can this work? As far as I know, only when we instantiate the class(create an object), then memory is allocated, but keyword 'static' needs to allocate memory instantly. I fear that every new object of this class type created will access a 'common' variable abc, like for example below:-

obj1.abc = 1;
obj2.abc = 2;

Result:- Both obj1.abc and obj2.abc will contain value 2. Is this interpretation correct?

Please help!

Correct. The correct syntax is:

obj1::abc = 1;
obj2::abc = 2;

Static members have global lifetime(are initialised as program start and last while the program runs), and class scope (only accessible via the class).
