You are assigning to abc.a twice without a sequence point inbetween so
this code is undefined as the order of evaluation of expressions
without a sequence point is unspecified.
Thanks for the speedy reply. But why this code:

        int a = 17, b = 16;
        a = a++ % 16;

results in a = 2 then? I think I need to know what is sequence point. 
I'll google that.

Thanks,
