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;

its not so much about dereferencing mama..ante in the context of this question..format specifier lo %ld %lld pettanu..okati long, inkoti long long..if long = int, then no problem..if long > int, then u have a problem..

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..

question: where did you get this "4 bytes" ,"8 Bytes"from ??
[quote author=Leader871 link=topic=127624.msg1411326#msg1411326 date=1291164824]
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

Segmentation fault ... It's writing to a random address.

may be they are type sizes. like int size and long size.

[andhrabalayya]

Pointers to different types of data are not guaranteed to be compatible in the language.  Substituting a pointer-to-long-int for a pointer-to-longlong is implementation dependent.

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..

again where did you get this "4 bytes" from ?  sCo_hmmthink

segmentation fault vastadi baa..we r trying to access some random address n trying to print the value of 4 bytes from the starting address

an int is not guaranteed to be 4 bytes.  In fact, its supposed to be the size of a processor's register, but even that's not always true.
