What output did you get when you ran this yourself? What output did you expect? Why was the output you got different than what you expected?

Don't waste time. Compile it and try out. Explain it using logical thinking.

in first can your output will be 28

because your a will get decremented after line execution completes

and in second case your output will be

-1
because as per precedence (right to left)
first increment operation will be carried out and then
substraction operation will be carried out.
a= a - ++a
