basic C questions are off-topic for this ng. you'd be better off asking
them in news:comp.lang.c or news:comp.lang.c.moderated. and believe it
or not, the comp.lang.c faq (there is a we version, search for it on
yahoo) is a good thing to read.

write what you mean. you mean 'i want p to point to b, right?
   p = &b;

>  p2=a[0]; // for this one I get a 'incompatible types in assignment'

again, you want p2 to to point to the first element of the array, you do
not want to assign a mystruct to p2.

   p2 = a;

or

   p2 = &a[0];

should work.
