Imagine if this same vector is copied around again and again (maybe in a loop); it should be pretty clear just how inefficient this is. The solution is to pass things around by const reference (or const pointer in C). The cost of passing things around by const reference is trivial and...
If you want to pass an arbitrary type by reference, you'd write something like T& t vectors are not special in this regard, just drop the parentheses. 1 2 3 voidinPlaceRotate(vector<vector<char> > &B){ B.size(); } Last edited onSep 15, 2018 at 1:55am ...
a reference or to use a pointer (something else I'm not familiar with). I've tried it, but to no avail. I think my problem might lie where I first write the function. I just want to be able to use the vector "intake" in "InputArrayFiller". Any and all help/comments are ...
For those implementingInvoke, Automation provides theDispGetParamfunction to retrieve parameters from the parameter vector and coerce them to the proper type. See Also Reference DispGetParam DISPPARAMS IDispatch::Invoke VARIANT and VARIANTARG IUnknown::AddRef ...

To be able to pass the object by reference, rather than this: int buf = j[ "int" ]; square( &buf ); j[ "int" ] = buf; And what is the actual behavior instead? Error (active) E0167 argument of type "nlohmann::basic_json<std::map, std::vector, std::string, bool, int64_t...

Of course, I could program second_function in a way that the multiple outputs would be compressed in a vector: function[a]=second_function(x,y,z) a(1)=...; a(2)=...; a(3)=...; But that adds further complications to the rest of my code. ...
error: binding reference of type 'Foam::vectorField& … ' to 'const Foam::Field<Foam::Vector<double> >' discards qualifiers and same error for the second line. Ok, ok. I still think is related with the temporal field reference. I've seen the way of ...
