Hey. I am confused on what is meant by 'adjacent' in this problem? Does it mean adjacent horizontally, vertically and diagoally?

Thanks

It is one long 1000 digit number, so there is no vertically or diagonally adjacent. It is only split over several lines so that it fits on the screen.

Find the greatest product of 13 consecutive digits in the 1000-digit number.

@programmer_:
If you'd read the topics in the pink box:
-you'd found that there already existed a topic for this problem
-you'd called your post "Problem 008" instead of "Problem 8"
Please make the work of the moderators as easy as possible and read and follow instructions.

Problem 8 gripe - PE ADMINS, please address issue!

To the admins, please read my comment on the forum for Project 8 solutions. This is STILL unclear, and I was able to FINALLY solve it via a whim I had. The problem is POORLY presented and confusing for such a simple solution.

Please don't create a new topic when one already exist for a problem.
It you had any doubt about the meaning of the question, I'm sure the existing topic here would have resolved them.

I've found that a solution for Problem 8 that produces a larger product than the answer the problem accepts as correct. The 13 digits I've found are adjacent.

This seems to leave you with at least two choices if you want to continue enjoying solving problems on Project Euler. i.e.:

A. Continue learning how to use the C programming language. Many other participants have already succeeded solving those problems using that language.
B. Start learning some other programming language. However, you may reach the same dilemma if you don't become sufficiently proficient in that other language.
When you assume something, you risk being wrong half the time.
