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::...
Now I want to sort the elements like vector of pairs are sorted. Only difference is that instead of 2 keys we have 3 keys here. After sorting the elements will look like: (1 4 4), (1 5 2), (1 5 6), (1 6 5), (2 8 3), (3 9 1). Is there any STL or other technique...
__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 (...

Is it possible to get the total contact force in a region of the model or for a contact pair in a Nastran analysis? Solution: Update Software Inventor Nastran version 2024.2 (and newer) can show the contact forces on selected contact pairs for some analysis types (line...
/// // 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++)...
(1) for a long enough time, typically from hundreds of ps to a few μs. We then obtain the excess spin observable vector δStot(t) from ρ(t) (Eq. S1-S2) and extract spin lifetime τs from δStot(t) using Eq. S3. Historically, two types of τs - spin relaxation time (or ...
Ahh, so a second thread reads from the other end of the FIFO, performs the work (strlen), and queues the results to the main thread on a results queue. The two threads communicate with a pair of half-duplex queues. Where do the results go?
