Hey guys , I found a question very similar to this on
cracktheinterview.com . I think it might clear some doubts . Here is
the question with answer : -
Whats wrong with the expression a[i]=i++; ? Whats a sequence point?
Although its surprising that an expression like i=i+1; is completely
valid, s
@priya...ya thats wat i meant by interleaving of operations(non-atomic
operations). you can understand the results if you can trace the register
values.

which order of execution will anyways give 22,13,14,14? The only way to
explain is interleaving of each of the operations(i.e operations are not
atomic).

it would be more accurate to call that behaviour (as in order of evaluation
of arguments) unspecified rather than undefined. It is compiler dependent
whether it takes from right to left or the other way round.

When you invoke the ++ operator (either pre- or post-increment) twice in the
same statement, you invoke undefined behavior. How your compiler decides to
resolve that is completely """compiler-dependent""". There is undefined
behaviour because the same variable is modified more than once between

Evaluation of b=a++ + ++a;
is also from right to left,
so
b = 22;
but i am getting the o/p as 22,13,13,13
