Can anyone explain how the output has come?

Question

When I do the 5 parts of the code separately I am getting output as
5 3 3 4 5
But when I combine all in one line it is giving output as
6 5 6 5 5
Can anybody explain why?

Answer 1

Avinesh so you telling that there is no reason for the output to come as so.
and I also want to tell you that the question I posted is a bit different from the question about which you are talking of. I asked to print value after each increment/decrement.

Answer 2

Avinesh I saw these posts but didn't get the answer for the second part of code. Could you please explain.

Answer 3

You can read the compiler warning, it is an undefined behaviour. It is discussed here.

Puthur Harthik Read from the 2nd thread that I shared. The order of evaluation is not so well defined in C and C++ unlike other languages like java etc.
