Answer must be 3, because post increment operator assigns value first and then incremented.
In DEV CPP while I run above program answer is 3.

@All above are wrong : Works from right to left.
The statement i = i++ means i == i + 1;.
Step 1: i = i + 1 results i = 4.
Step 2: i = 4.
The statement i = i++ means i == i + 1;.
Step 1: i = i + 1 results i = 4.
Step 2: i = 4.

No, the actual answer is 3 because it is the dependent expression the value of I will assigned to the left side and than value incremented.

@Rishabh.
You're damn right! the answer is 3 in case of such post increment.
i = i++;
is analogous to
temp = i;
i = i + 1;
i = temp;

It is wrong because of i=3;
i=i++;
first i=4;
seound i++=3;
than
i=i++;
So, i++ override the value of i;
The output will be 3;.
i=i++;
first i=4;
seound i++=3;
than
i=i++;
So, i++ override the value of i;
The output will be 3;.

Answer will be 3.
i=i++
i=3++
I take the value 3 there won't be an increment.
Priority will be given to i=3 not to i++.
i=i++
i=3++
I take the value 3 there won't be an increment.
Priority will be given to i=3 not to i++.

Isn't it depend on the compiler. I mean in c++,
int x = 10;
x = ++x;
cout<<x;
it will still give 10 as output.
int x = 10;
x = ++x;
cout<<x;
it will still give 10 as output.

Correct answer is 4.
because i=3
i=i++ // this is post increment so i=3 but internally i is increment by 1.
so i=4.
because i=3
i=i++ // this is post increment so i=3 but internally i is increment by 1.
so i=4.

I am very appreciate you to give me such like chance to see myself how I understand the course!!!!
Thanks to you!
Thanks to you!

All of you are wrong. The post-increment effect is damaged by the assignment operator. Thus the value of i=3.
