struct, array, pointer

ex:

struct people{

        int age;

        int height;

};

struct people a[10];

&a: bffff988  a:bffff988  &a[0]: bffff988  &a[1]:bffff990  (a+1):bffff990

because the size of struct people is 8,  (a+1)= &a[1]- &a[0]= bffff988+ 8= bffff990

struct people *b=a;

b+1 equals a+1

b[1] equals a[1]
