C programming ( structs)

Question

I am have one question. Lets say we have a struct which is defined as follows:

 typedef struct test { 
   int x;
   int y;
 };

Now if I create a instance of this struct as follows;

  test object;

So will the " &object == &object.x "??

You probably meant `typedef struct { ... } test;`. This is not related to the question you asked (which has been answered since), but it's generally a good idea to post actual code. — dxiv, Nov 21 '15 at 22:29

Yes the address of the first data member of the structure will be equal to the address of the object of the structure itself.

From the C Standard (6.7.2.1 Structure and union specifiers)

15 Within a structure object, the non-bit-field members and the units in which bit-fields reside have addresses that increase in the order in which they are declared. A pointer to a structure object, suitably converted, points to its initial member (or if that member is a bit-field, then to the unit in which it resides), and vice versa. There may be unnamed padding within a structure object, but not at its beginning.
