std::pair Defined in header<utility> template< classT1, classT2 >structpair; std::pairis a class template that provides a way to store two heterogeneous objects as a single unit. A pair is a specific case of astd::tuplewith two elements. ...
For this, we usetie()function, which unpacks the tuple. Below is the example of using tuple in C++. #include <bits/stdc++.h>usingnamespacestd;intmain() {//define a tuple of <roll,marks,name>tuple<int,int, string>student;//create the pairstudent=make_tuple(1,80,"XYZ");//extract...
std::list<std::pair<A,B> > 与 std::map<A,B> 的区别 std::mapis optimized for fast searching. It has its ownfindmethod that uses its internal structure to provide good performance. In general, it will only inspectlog(N)keys, where N is the number of items in the map. std::list...
then later in the code there is a statement fst::StdToLatticeMapper<BaseFloat> mapper; which generates errors like this 1>c:\users\yenda\downloads\kaldi\src\latbin\lattice-compose.cc(49): error C2872: 'int32': ambiguous symbol 1> c:\users\yenda\downloads\kaldi\tools\openfstwin-1.3....
