Include the error message within code wherever needed: cout << "I am an error message!" < 135k20234273 asked May 26 '13 at 18:47 polerto 77411637 The first way is not very localization-friendly. –qdii May 26 '13 at 18:52 1 Exception handling? –Rapptz May 26 '13 at 18:52 5 ...Aaaaaaand, error messages go to cerr, not to cout. –user529758 May 26 '13 at 18:54 ...or 4. Load the messages from external file. –milleniumbug May 26 '13 at 20:18 It's nice to remember that some libraries offers features that may change one's perspective on this. For example, Qt (which is mainly for C++) has its own translation system with QObject::tr() + the whole translation system with QtLinguist which makes the idea of error messages in one place quite unnecessary (repetitions are easily handled with global replace Ctrl+Shift+R in Qt Creator). So I suggest one should always learn the translation features of one's development environment before making this decision. –Momergil Jan 13 '15 at 16:14 add a comment| 2 Answers 2 active oldest votes up vote 4 down vote accepted It is all a matter of preference with both benefits and downfalls. Hard-coding string literals at the site of the error may be harder to maintain but it also is easier to read in my honest opinion. for example cout << "You were unable to login. " << "Pl #error inside of python error messages a conditional that detects a combination of html error messages parameters which you know the program does not properly support. For example, if you know that the program will not run properly on a VAX, you might write #ifdef __vax__ http://stackoverflow.com/questions/16762545/what-is-the-preferred-way-to-include-error-messages-in-c #error "Won't work on VAXen. See comments at get_last_object." #endif If you have several configuration parameters that must be set up by the installation in a consistent way, you can use conditionals to detect an inconsistency and report http://gcc.gnu.org/onlinedocs/gcc-3.3.5/cpp/Diagnostics.html it with #error. For example, #if !defined(UNALIGNED_INT_ASM_OP) && defined(DWARF2_DEBUGGING_INFO) #error "DWARF2_DEBUGGING_INFO requires UNALIGNED_INT_ASM_OP." #endif The directive #warning is like #error, but causes the preprocessor to issue a warning and continue preprocessing. The tokens following #warning are used as the warning message. You might use #warning in obsolete header files, with a message directing the user to the header file which should be used instead. Neither #error nor #warning macro-expands its argument. Internal whitespace sequences are each replaced with a single space. The line must consist of complete tokens. It is wisest to make the argument of these directives be a single string constant; this avoids problems with apostrophes and the like. sign up log in tour help Tour Start here for a quick overview of the site Help Center Detailed answers to any questions you might have Meta Discuss the workings and policies of this site About Us Learn http://codegolf.stackexchange.com/questions/1956/generate-the-longest-error-message-in-c more about Stack Overflow the company Business Learn more about hiring developers or posting ads with us Programming Puzzles & Code Golf Questions Tags Users Badges Unanswered Ask Question _ Programming Puzzles & Code Golf Stack Exchange https://www.reddit.com/r/cpp/comments/35tcvs/visual_c_quality_of_error_messages/ is a question and answer site for programming puzzle enthusiasts and code golfers.

The score of each entry is the number of characters in the longest error message the compiler emitted. Types included in your source code and quoted by the compiler are cpp error messages counted as a single character. Cheating You can always redefine a template in template in template with long names, but I expect something creative. I tried to prevent some of that by the last rule, but of course the rules can be better, and I'll be glad for improvements. code-challenge c++ kolmogorov-complexity share|improve this question edited Apr 4 '11 at 22:03 dmckee 2,04321433 asked Apr 4 '11 at 16:13 Elazar Leibovich 363135 2 Edited the tags. I admit that [kolmogorov-complexity] is a bit of a stretch, but I think it is expressive in this case. –dmckee Apr 4 '11 at 22:04 12 Maybe you should go for a ratio: Error.message.length / code.length. –user unknown Jun 30 '11 at 16:28 Related: codegolf.stackexchange.com/questions/5802/… –Ilmari Karonen Nov 20 '15 at 20:37 add a comment| 13 Answers 13 active oldest votes up vote 38 down vote accepted Template error messages are fun to decipher.
