Answer will be 3, not 4. Just compile it on another online compiler. And conceptually also it should be 3.

@Suraj.

Answers will be 4, 3 in post increment value will be assigned later incremented so j=3 and i=4.

The ans is 3 not 4,

Here, i=i++ is divided into temp=i; i=i++; i=temp so the i value remains unchanged.

The answer will be 3 because first the value is assigned to i then it is postdecremented.So i will be 3.

Then what abt i-- ? Anyone can clear my doubt?

i=5, j=7;

printf("%d %d %d %d", ++i, ++j, i++, j++);

3 is the correct answer.
As x=++i i.e. y=++i
At the place of x, any other variable can be there.

How answer came 4? It's post-increment operator we 1st assign the value 3 then value will increase

I tried this code in DEV C++ blog and I got the output as 3. But here, the compiler says 4. Why?
