Answer / vadivel t

The below line u can use for the question asked, provided
the address is not pointing to any OS memory, system files
or any location on ROM memory.

0x2000 is invalid address(Access voilation)in my system. So
I tried with the valid address 0x12FF70 to get the o/p.

main()
{
*(int *)(0x12FF70)= 20;
printf("%d \n",*(int *)(0x12FF70));
getch();
}

O/p would be 20.
