CRect c;

defines an object

CRect c();

declares a function returns CRect object.

Sometimes people are not aware of second form and get caught by most vexing parse.

This one

CRect c;

creates a CRect object called c.

This one

CRect c();

declares a function called c() that returns a CRect object. It is a parse that is vexing, however, it isn't the most vexing one.
