I don't believe there is a difference. I think it's just a matter of coding standards.

It's the same.

Yep, almost all spaces (except those between keywords) are ignorable, so in the end the compiler would just see it as
int*aanyway.

From a language standpoint there's no difference. However, placing the asterisk by the variable makes more sense when you have multiple variables in a declaration:
int *p, *q;The reason this makes more sense is because when the asterisk is paired with the type, it's easy to forget that it only applies to the first variable:
int* p, q; // q should be a pointer, but it's notAnd of course, when you fix that error, it just looks funny:
int* p, *q;If you only have a single variable per declaration, it's not an issue and you can do whatever you think makes more sense. The problems only show up with multiple variables per declaration.

This is relevant to the OP and the previous post's questions how???
This:
int* a, b;Is not the same as this:
int *a, *b;The first one produces an integer pointer called "a" and an integer called "b". It is a confusing and misleading formatting style that makes it look like the '*' extends to "b" when, in actuality, it does not.
The second produces 2 integer pointers called "a" and "b". The '*' operator associates with the variable name, not the datatype. It's area of effect does not extend past the first comma operator (',') to the right.
