Answer 1

increment operation in printf is done from right to left

Answer 2

the problem is that, it's incremented normally, but printed in reverse, though I haven't figure out why it work that way, but that's how it works, let me call on my guru ~ swim ~ to shed more light on this

Answer 3

But then shouldn't the second printf give 0 0 as the second printf is (i++,i)??

Answer 4

It's because when you first use I, i++ at that time first value is look like this
0, 0++ so in this statement I=0 is post increment by 0++ so value of i become 1 but 0++ is still give 0
So output 1 , 0
In other statement i++, i
0++, 0
First statement 0++ will give 0 and next time post increment give 1 so output comes as 0, 1
