This discussion board is a place to discuss our Daily Challenges and the math and science
related to those challenges. Explanations are more than just a solution — they should
explain the steps and thinking strategies that you used to obtain the solution. Comments
should further the discussion of math and science.
When posting on Brilliant:
Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

When you use a++ operator it first prints the value of a then increments its value. so first the value of $a = 7$ gets printed then its value gets incremented to $8$. After this when you use the ++a operator, it first increments the value of $a$ then prints it so first the value to a is increased to 9 then it is printed.
In short the post increment operator (a++) increments the value of a after the command given to it while the pre increment operator (++a) first increments the value of a then it is used in the command given to it.
Cascading cout statements are initialized from right to left. Though as Agnishom mentioned, this isn't a good idea, such questions commonly come for Viva.

I asked this from my CS teacher and she said that the output depended on which compiler we are using.
Different compilers could give different output. Is it so??

Actually the cascading took place from right to left as after postfix(++a) .It becomes the last updated value i.e 8 . So compiler starts reading the output from right to left.
The answer is 888..
Bcoz cout has a right to left associativity... So the answer mostly depends on compailer...in right to left associative answer is 888...

I too thought of the same output but my compiler gave it out as '888'. Well, thank you for the views.

Now that I am an ex-student, I should probably drop an email to our CS teacher.

Actually, coding like this is ambiguous and considered a bad idea

Yes totally agreed.
