using std::find() on std::string vectors
|
| |
Hello All, I have a question on the use of std::find() on a vector that contains std::string objects. When I need to do a search on a vector of strings, I currently use the std::find() algorithm, e.g. : std::vector<std::string>::iter ator theIterator; theIterator = std::find ( vecStrings.begin(),... more »

PERFORMANCE IN VISUAL STUDIO 2008 + STL.
|
| |
Hi Group, We recently migrated our project from VS 2003 to VS 2005 and found that our runtime performance in release mode has degraded by a factor of 3. On investigation we found that it was due to stl in VS 2005. Building with STLPort confirmed this. As of now we are not in a position to migrate to... more »

STL container performance
|
| |
I am suffering performance problems with the STL implementation in Microsoft Visual Studio 2005. There are indications that it is down to either memory management or some locking contention. As an example, the WordCount sample at [link] running on a 100Mb text file executes in 1 minute 39 seconds when... more »

|

(The console can display UTF_16 just fine if you change the font to lucida console - easiest verified with adding a filename with some greek or cyrillic characters in it and calling dir) Now, my problem is, that the default wcout stream on windows will... more »

Memory allocation of std::list
|
| |
struct Item { int *pPtr; std::list<int*> intList; ...Item *pItem = new Item[1700000]; I expected the memory usage would be (sizeof(Item) * 1700000) + (the head pointer of list * 1700000), ie. (28+12)*1700000 = ~64MB, but the outcome is about 170MB. Would you tell me why is it so? I asked this question in the MSDN forums and someone answered me "You should... more »

Make copy of input stream
|
| |
Is it possible to make a copy of an input stream? I would like to make a copy of an input stream which uses the same buffer as the original but has its own position and state which are initialized to the original stream's position and state. I am not seeing this in Josuttis but wanted to ask in case I am missing something.... more »
