I am creating an XYZ.txt file in my project,
i want that each time the XYZ.txt is created the name must be not simple as XYZ.txt, but it must be XYZ_DATE_TIME.txt

XYZ_27-08-2008_02-12.txt
XYZ_27-08-2008_16-45.txt

Is there a memory leak here; The only diff is here we create the object of the class A as static.

That is a memory leak by design.
