Join Dan Gookin for an in-depth discussion in this video Solution overview, part of Code Clinic: C (2015).
- This chapter's assignment caused me…more consternation than any other.…I stewed on it for far too long.…I did what any sane programmer would do.…I did anything other than programming.…I played a computer game.…I went outside.…I even talked with a girl.…These distractions proved beneficial.…By removing my mind from the details of the ordeal,…I was able to see the big picture.…Searching for a subimage is like…searching for anything.…It's a needle in a haystack problem.…You can use C to search for a string of texts…inside a large document,…and that's effectively what the solution…to this puzzle involves.…
The assignment is to compare two images.…I could do just that.…Having the code required two file names…as command line arguments.…Simple.…Another approach would be…to have a source file name specified as an argument,…and then specify a directory as the second argument.…The code would then scrub through the directory,…and compare each file in that directory to the source.…A final approach would be…to simply scan the entire directory…
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.
