New updates of C++Hints, service of recommendations on C++ programming

Changes in CppHints.com

by PVS-Studio Team

We got a lot of positive feedback from our readers and continue developing the C++Hints project. We have also answered two requests, that we saw quite often in the letters:

• The RSS feed is added (http://cpphints.com/rss)
• The up-to-date full list of hints is created at: http://cpphints.com/archive

By this moment we have published the following articles:

• Why incorrect code works
• Don't forget that the loop termination conditions are always evaluated completely
• Undefined behavior is closer than you think
• Visual C++ and wprintf() function
• Use a prefix increment operator (++i) in iterators instead of a postfix (i++) operator
• Avoid using a macro if you can use a simple function
• Don't name functions "empty"
• Hot on the heels
• Make your code more stable
• Insidious VARIANT_BOOL
• Do not compare 'this' to nullptr anymore
• Use the keyword "override" when overriding virtual functions
• Evaluate the string literal length automatically
• Do not use #pragma warning(default:X)
• Table-style formatting (continuation)
• Make sure you work with data in streams the right way
• Delegating constructors make life easier
• Use dedicated functions to clear private data
• Table-style formatting
• Don't spare code lines
• Start using enum class in your code, if possible
• A good compiler and coding style aren't always enough
• When using Copy-Paste, be especially careful with the last lines
• Don't try to squeeze as many operations as possible in one line
• Use the '\0' literal for the terminal null character
• Avoid using multiple small #ifdef blocks
• Beware of throwing exceptions in destructors
• Check all the fragments where a pointer is explicitly cast to integer types
• Do not call the alloca() function inside loops
• Don't Do the Compiler's Job
• Use available tools to analyze your code
• Larger than 0 does not mean 1
• Copy once, check thrice
• Beware of the ?: operator and enclose it in parentheses

An introduction to C++'s SFINAE concept -- Jean Guegant

Jean Guegant describes in a very detailed way different implementation stategies of compile-time introspection of a class member for C++98, C++11 and C++14.

An introduction to C++'s SFINAE concept: compile-time introspection of a class member

by Jean Guegant

From the article:

As a C++ enthusiast, I usually follow the annual C++ conference cppconf or at least try to keep myself up-to-date with the major events that happen there. One way to catch up, if you can't afford a plane ticket or the ticket, is to follow the youtube channel dedicated to this conference. This year, I was impressed by Louis Dionne talk entitled "C++ Metaprogramming: A Paradigm Shift". One feature called is_valid that can be found in Louis's Boost.Hana library particulary caught my attention. This genious is_valid function heavily rely on an even more "magic" C++ programming technique coined with the term SFINAE discovered at the end of the previous century. If this acronym doesn't speak to you, don't be scared, we are going to dive straight in the subject.
