Answer Posted / yathish m yadav
the output is "hello".
here we are overwriting pointer *p thrice.
that is in the function we get an piece of memory from
malloc and assigned to p,
in the statement strcpy(p,"hello");
the malloc memory is lost and the compiler creates an char
array and copies the string "hello" and it makes the
character array as constant.
