Compile and run it with the following command:

gcc vm$.$c && $./$a$.$out $10$

Let's say we get the following output:

$(181980)$ addr pointed to by p: $0$x$405260$

$(181980)$ value of $(*$p$)$: $11$

$(181980)$ value of $(*$p$)$: $12$

$(181980)$ value of $(*$p$)$: $13$

$(181980)$ value of $(*$p$)$: $14$

$(181980)$ value of $(*$p$)$: $15$

Which section of the virtual memory space of this program$/$process is used to store the printed$-$out value $"0$x$405260"?($Note that p is a local variable of integer pointer data type.$)$
