| Christiano <christiano@engineer.com>: Sep 12 12:09PM -0300 Errata (my version) is here: https://chcpp.info/index.php/2017/09/12/programming-principles-and-practice-using-c-2nd-edition-bugs/ Working library for chapter 12-16 https://chcpp.info/index.php/2017/07/02/programming-principles-and-practice-using-c-chapter-12-to-16-how-to-compile/ The official library[1] has a lot of problems. In my opinion the library above is the best alternative at the moment. In the chapter about Numerics, use this: http://stroustrup.com/Programming/PPP2code/Matrix11.h http://stroustrup.com/Programming/PPP2code/MatrixIO11.h [1] http://stroustrup.com/Programming/PPP2code/ |

Unsigned types pervade standard C++ so you "disliking" them is irrelevant. /Flibble |

When the student reaches the chapter 12, he faces the following situation: He can't even compile the first example, because there are a lot of problems with the official library of PPP second edition. I believe that there was some mistake when the files were uploaded, example: It was uploaded old files, not the latest files. There are workarounds for this situation, example: https://groups.google.com/forum/#!topic/ppp-public/BtlzdWGuQpQ But it was not sufficient. So, I got the library for 1st edition (that works) and worked on it in order to match with the book 2nd edition and it being able to compile in several platforms as FreeBSD, Linux, Windows, MacOSX. My work is a result of initial Stroustrup 1st edition library + Code printed in the book 2nd edition + Bug corrections + Corrections to compile in several platforms It would be unfair to say that it is my library, when I say "my library", it is just a way to separate things better. I prefer call it of Ch12new library. Of course, the Stroustrup GUI library is not a General professional GUI library like FLTK, Qt, WxWidgets, but nobody is saying that. It is only a good manner that the author found in order to introduces the students to topics like: - callbacks - polymorphism - inheritance - interfaces In this way, the student can create Shapes which inherits class Shape and has a virtual method "draw_lines" in order to "system" draw the Student's shape on the screen using an uniform interface receiving Shape*. When I said "have a lot of problems" I'm trying to say that it simply does not compile or it doesn't match with the book 2nd edition. |

| "Rick C. Hodgin" <rick.c.hodgin@gmail.com>: Sep 12 11:35AM -0700 You must be born again. If you are not born again, you remain in your sin and you are going to Hell and will burn in eternal Hell fire forever. If your sins are forgiven, you are a new creation that is unlike the world. One God, One Way -- A sermon to change your life forever https://www.youtube.com/watch?v=6m38NAhi_r4 Do you have sin? You need to be forgiven. Jesus came to this Earth to forgive you. Ask Him to forgive you today. Right now. And you will receive the free gift of eternal life in Heaven with God in a new body like the angels that does not wear out or tire. Jesus Christ wants to forgive your sin more than He wants to judge you. But He will judge you if you do not receive this last ditch effort to save your soul given to you by God in this world. His sacrifice on the cross is enough for you. Ask Him to forgive your sin and you will live on after you leave this world. May God pour out the blessing of hearing and understanding upon your soul. Love you, Rick C. Hodgin |
