Remove unneeded function declaration in 7-06 2016-11-21T08:04:34Z zlg zlg@zlg.space 2016-11-21T08:04:34Z urn:sha1:55e5e56ff1eae9b6234ec885b4fc6fee907d1e75 Solve Exercise 7-6: simple `diff` utility 2016-11-17T15:34:18Z zlg zlg@zlg.space 2016-11-17T15:34:18Z urn:sha1:54b3475b3041bf35c25bfad2f521d5751e6eadbf Actually run astyle on the file... 2016-10-12T13:54:44Z zlg zlg@zlg.space 2016-10-12T13:54:44Z urn:sha1:ce7f0379df5dbfca9b86492ea5d2993196a1cc52 Solve Exercise 7-5: RPN calculator with scanf() 2016-10-12T13:49:26Z zlg zlg@zlg.space 2016-10-12T13:49:26Z urn:sha1:edf72affee48c3e6530d6f60142d834eecae8aa3 This exercise was deceptively simple, and ended up simpler than the original! The *scanf series of functions is very useful, but you also have to be careful or you'll run into segfaults. Solve Exercise 7-4: minscanf() 2016-06-30T10:56:52Z zlg zlg@zlg.space 2016-06-30T10:56:52Z urn:sha1:3aa9b1189dc7ee6660a2b7123ee9a00df0f9ca09 This one wasn't too bad, either! There's a minor bug in the code, but I'm not sure how to fix it. It *technically* meets muster, though. :P Solve Exercise 7-3: minprintf() 2016-06-26T09:57:18Z zlg zlg@zlg.space 2016-06-26T09:57:18Z urn:sha1:a8db504e7d098123075bd00d2a998488a97af81d The massive astyle sweep! 2016-06-16T17:15:33Z zlg zlg@zlg.space 2016-06-16T17:15:33Z urn:sha1:f8d9ff23eb8d3e3286ff5cf4d5f9493532991bb7 Code style should be consistent now. All future commits will be run through astyle or they will be amended. Solve Exercise 7-2: Format arbitrary input 2016-06-16T16:51:16Z zlg zlg@zlg.space 2016-06-16T16:51:16Z urn:sha1:82656bf5aa4edd668e1adc3faa8148251509b912 The solution is technically not 100% correct, but good luck figuring out a robust solution inside Category-0 restrictions. Unicode characters like ¬ or ♥ show up as 64-bit hex codes and I couldn't find a way to shorten them. Then again, UTF-8 supports characters up to 8 bytes long. Use it with plain ASCII and it looks only minorly off. Solve Exercise 7-1: `upper` and `lower` 2015-12-08T11:10:43Z zlg zlg@zlg.space 2015-12-08T11:10:43Z urn:sha1:ea3c92d58cdf2d4030598d1052c2eb6cf2d8cc7e Two cases, one file. This exercise was a welcome departure from the recent head-scratchers. It made me think about a solution for the pathname issue I realized would crop up, too. I'm roughly 75% done with the book! Maybe by the time I finish it, I'll have a Makefile ready for the project...
