Errata
Corrections to Everyday Programming, Volume I: Basics of Computer Programs, First Edition, published by Intramotev Press.
Every book of four hundred pages has mistakes in it, and a book with more than a thousand code listings has more opportunities than most. Confirmed corrections are listed here as they are found, so that a reader who hits a puzzling passage can check whether the puzzle is theirs or the book’s.
No errata reported yet for the First Edition.
That is a statement about what has been reported, not a claim that the book is perfect. If you have found something, the section below is how to tell us.
How to report an error
Please report anything that looks wrong — the small ones matter as much as the large ones, and a typo that costs a beginner an hour is not a small one.
The most useful reports are on GitHub Issues, because the thread stays visible to other readers who hit the same thing. If you would rather not use GitHub, email works too.
When you report, please include:
- Where. The printed page number, or the section or exercise number —
Exercise 9.4.2is unambiguous and identical in print and on this site. - What it says. A short quotation is ideal.
- What you think it should say, and briefly why.
- Which format you were reading: the printed book, the sample PDF, or a page on this site.
What counts
Worth reporting:
- Code that does not run, or that runs and produces a different result from the one shown in the comment.
- A solution that misdiagnoses its bug, or fixes a different bug from the one in the exercise.
- A definition, formula, or claim that is factually wrong.
- A cross-reference pointing at the wrong chapter, section, figure, or exercise.
- Typos that change the meaning —
=where==was meant, a droppednot, a wrong variable name in a listing.
Probably not errata, though still worth raising:
- Style preferences, or a different way you would have written a program.
- Anything about the exercise numbering: it is deliberately sparse, because the numbers follow the chapter and section that host each exercise rather than running consecutively.
Errata in the exercises
The exercise and solution pages on this site are generated directly from the book’s source, so a correction to the book propagates here automatically on the next build. If a program on this site disagrees with the same program in the printed book, the printed book is the older of the two — please report it either way, since a disagreement is itself a defect.
Reported errors are credited by name on this page unless you ask otherwise.
