Well, you generally can't copy an integer quantity into a variable that holds a pointer quantity. The types don't match. There are no language-defined rules for what happens when you play with pointers this way. It is up to the operating system and compiler(segmentation fault). The language only defines what happens when you code within the confines of the language's specifications.  This sort of thing is outside the bounds of the language specifications.

Ohh yaa..type match avvadhu correct ee..kani pointer kuda uninitialized ee kadhaa..i mean a pointer should point to some thing kadha baa..am i missing some thing here..

Umm sorry chudaledu...
No, the * in that case does not mean 'dereference'.  it is a part of the type of the variable. So "a" itself is a pointer-to-int, and you're initializing it with the address 5.  The int that is at address 5 is at the moment unknown.
If you had done this:

int *a;
*a = 5;

then the first * is part of the data type, but the second is dereferencing.  In this case, "a" is an uninitialized pointer, and you are trying to set the int at some random address to 5. Distinct difference.

printf("%d',*a) answer 5 aa baa

Ok one more interesting problem..

int a=5;

printf("%lld",*(long *)(&a));

printf("%ld",*(long *)(&a));

Pointer should point to address of what u store. In int *p, int is not type of pointer. int is type of the number what we store at a address which is pointed by p.
Am i correct.

kadu baa..
pointer anedi edoka address ki point cheyali..right now when u say int *p it is pointing to some random value..if it were some thing like..
int a=5,*p;

p = &a;
and then print *p u get a 5..
