@programming love:I can understand what u say but my doubt is that for the first output which is 2, according to your example, p has address 10 which it points to.And as u say int * tends to dereference 2 bytes so that wud be now 10 and 11.finally char * takes only 1 byte so why is value at 11 address printed( i mean 02) and not value at 10 address( 00)
similarly for the second output where u say p+1 goes from 10 to 11 due to char type.when u do int* u say it dereferences 11 and 12. so then when char * is done finally why does it print the one at 12 and not 11? please correct my understanding if wrong On Mon, Aug 15, 2011 at 10:44 AM, programming love < love.for.programm...@gmail.com> wrote: > The internal representation of array is this: > > suppose that the address starts from decimal number 10 and integer occupies > 2 bytes > > 10- 0002 ( num 2 in hex) > 12- 0003 ( num 3 in hex) > 14- 0004 ( num 4 in hex) > > Now p points to address 10 and is type char.
