I\'ve been writing a multi-threaded DLL for database access using ADO/ODBC for use with a legacy application. I need to keep multiple database connections for each thread, so I\'ve put the ADO objects
This looks simple but I am confused: The way I create a vector of hundred, say, ints is std::vector<int>*pVect = new std::vector<int>(100);
Why this code does not compile (Cygwin)? #include <开发者_如何学JAVAvector> template <class Ttile>
I am new to Emacs, and I have the following code as a sample. I have installed GNU Emacs 23.1.1 (i386-mingw-nt6.1.7600), installed cedet-1.0pre7.tar.gz. , installed ELPA, and company.
std::vector<Foo> vec; Foo foo(...); assert(vec.size() == 0); vec.reserve(100); // I\'ve reserved 100 elems
After a lot of investigations with v开发者_开发问答algrind, I\'ve made the conclusion that std::vector makes a copy of an object you want to push_back.
So, I have a vector std::vector<std::string> lines. I fill this vector up, and can access it like
I was looking through the std::vector code and I found something I didn\'t quite get. When capacity < size() + 1 it needs to reallocate the buffer so it can insert the new element. What it does (as
I have a buffer class in my C++ application as follows: class Buffer { public: Buffer(size_t res): _rpos(0), _wpos(0)
inline void add(const DataStruct& rhs) { using namespace boost::assign; vec.reserve(vec.size() + 3);
