Join Dan Gookin for an in-depth discussion in this video Processing a table via standard input, part of Code Clinic: C.
- In this movie I explore the second part of my solution…to the Lake Pend Oreille problem.…That is, how to read as input a table of variable size.…There's gonna be different numbers of rows,…depending on the date.…To handle that text, I wrote a program called "crunch_data",…which eats specific output from the "fetch_data" program.…Of course, I could have just written…one big program to do everything.…By splitting the chore…between fetching and crunching, however,…I allow the user some options.…For example, the fetch_data program…could be run on a schedule,…storing information if need be.…
Then crunch_data can be used as necessary.…To fulfill the assignment, however,…both programs are run together.…With the output of fetch_data, fed as input to crunch_data.…Crunch_data is a filter.…Like any filter, it reads standard input…and generates standard output.…For this code, the input is expected to be…the specific format generated by the fetch_data program…covered in an earlier movie.…First, command line options are processed.…
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.
