In the following example, we use <int, string> pairs and the syntax to add an element to the vector of pairs is push_back(make_pair(55, "fifty-five")).#include <iostream> #include <vector> using std::cin; using std::cout; using std::endl; using std::make_pair; using std::...
__typeof__. The examples in this article do not make use of the double underscore convention. Syntactically, thetypeofkeyword is followed by parentheses which contain either the name of a type or an expression. This is similar to the possible operands which are accepted by thesizeofkeyword (...
In general, you will want to support both the Collections and Generic interfaces so that clients currently using the Collections interfaces will be able to use your types. Here is how you might declare support for both:Copy template <class T> ref class vector : System::Collections::...

/// // Original, single-threaded implementation /// std::vector<std::pair<int, int>> corres; corres.reserve(std::max(nPti, nPtj) / 4); // reserve 1/4 of the maximum number of points, which is heuristic /// /// INITIAL MATCHING /// for (int j = 0; j < nPtj; j++)...
In cool leg, we teach CS undergrads to protect their multi-threaded data structures with a lock. This is probably a Test-and-Set (TAS) lock, and if they went to a good university, they have a homework assignment where they are told to uselock cmpxchgto implement a mutex. Once they're...
A visualization of the complete URS can be found in Fig. 2. To use URS, the softmax output of the VG model is first obtained by giving it an image, a free form natural language command, and a set of objects that have been extracted with a Region Proposal Network (RPN). Next, URS...
where the distance and force are vector quantities. If the selected reference point is not chosen properly, the distance will be incorrect and the moment results will be "wrong". For example, a cantilever beam with a moment load will have contact reaction forces that sum...
