Use of facet codecvt for indenting output text
Hello, I'm looking for implementing a way to indent some data fed to an std::ostream. I found this link: that proposes to use a facet; I think it is a good idea (and having the opportunity to work with locales for the first ti... 20 Jan 2010 09:29
Generic compare function
Why C++ does not contain a generic compare function? Such function would return a negative value if left < right, zero if left == right and a positive value if left > right. It could be either overloaded for user types or like swap use some template magic. Such function would be useful in cases when obj... 21 Jan 2010 21:25

Iterating over vectors - speed difference
Hi I am comparing the runtime of iterating through a vector using 3 different approaches - 1) Indexing -> i = 0; i < vec.size(); 2) Iterator -> i = vec.begin(), i != vec.end() 3) Summing using Accumulate Here are the runtimes on my computer. I am compiling using VC++ 2008, Release mode build. Runtimes are pr... 6 Jan 2010 08:30
Tricky declarators
It is well established that "int (*) (int)" is a pointer to a function that takes an integer and returns an int. But what about spelling the type of a function that takes and integer and returns an int. By first though was perhaps "int ()(int)", but Comeau C++ interpets that as a function that takes an int and re... 26 Dec 2009 14:22
