Assuming that we have the code
That is wrong and dangerous of course because pointer is uninitialized and it has no a known address.Code:int *p *p = 2;
Some books they write that p will modify the code data (program code) if p happens to have an address of program code of course.
I think this is not true on the linux because of
the memory layout of processes....
assuming this scheme ->
the TEXT segment which has the code of the program is ROM . Hence we can't modify its contents even if p points to this area.
