Join Dan Gookin for an in-depth discussion in this video Creating a two-dimensional array solution, part of Code Clinic: C.
- Despite success with the N-Queens code,…I wanted to try it again.…Specifically, I wanted to work on the recursive routine…to ensure that I fully understood the diagonal attack.…Because my stumbling block was the single-dimension array,…I figured I would return back to…a two-dimensional character array.…Unlike my first disastrous attempt to solve this problem,…I would track only the queen's location,…and not her attack vectors.…So, this third solution was really a combination…of both my previous attempts.…With the emphasis on making a diagonal attack…easier for me to code.…
Two-dimensional character array is faked right here,…at line 62.…I use a pointer instead of two-dimensional array notation…simply because this is the C-language,…and pointers are a big deal.…Of course, that also requires some pointer math,…but for some reason,…my brain could handle that type of math…better than the row-column thing…going on with the single-dimension integer array,…as covered in the previous movie.…Space is allocated for the array.…
Dan introduces challenges and then provides an overview of his solutions in C. Challenges include topics such as statistical analysis, searching directories for images, and accessing peripheral devices.
