Ok one more interesting problem..

int a=5;

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

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

umm...Now, on all common 32 bit OSes, long and int are the same size, so the second line is likely to print 5. On many 64 bit OS'es, however, long is larger than int, so the second line may print garbage, and is undefined behavior. The first line is wrong on all OS'es. If a long is larger than an int, then in practice you will usually get a long value where half of it is 5 and the other half is garbage. One problem is that the %lld format specifier is for a long long, and you are passing it a long. The second problem is that &a points to an int, and you cast it to a long and then dereference it, which is undefined.

well actually %lld is sufficient and i dont have to cast it to a long..
printf(%lld",p);

it would try to print out 8 bytes from that p's starting address..

error kadu..warning vastadi obviously 1st daniki..
%lld ante long long..usually long long size is bigger than that of an int..so aa p ki sambandinchina 4 bytes kakunda inkoka 4 bytes..motham 8 bytes lo unde value print avutundi..assuming long long is 8 bytes lng

second daniki 5 print avuthundha?

i can write that statement as follows:  long *p; p=&a;
*p=?    p is address of a...When we dereference it , we get storage value = 5;

mama garbage ante enti..it is quite common to find this term in basic textbooks..at least nenu first chadivinappudu garbage ante ento ankunevaadini..
lets say u declare a variable and dont initialize it..assuming it is a local variable..stack lo memory allocate avthadi..aa particular address lo previous ga unna value alane untadi andulo..so print cheste neku kavaalsina or expctd value raadu..or inka neat ga cheppalante evadoo vaadesina memory ni nuvvu unchukuntunav..so garbage ani antaaru..
