Answer Posted / sharan
when u declare a structure there is no memory allocated yet.
memory will be allocated after creating an
instance(variable).Here, there is an instance (pointer
variable pointing to structure FAQ ). But the compiler
allocated only 4 bytes of memory for the variable temp. But
the this temp contains garbage address or 0 if it is
global. to allocated memory of size 60 byte u need to use
malloc function.
Ex: temp = malloc ( sizeof ( struct FAQ ) );
now 60 bytes of memory has been allocated from the heap. and
the starting address of this memory chunk is stored in
variable temp.
