For example, pass vector reference // caller.cc std::vector<string> chip_ids; fn(chip_ids) //callee.cc void fn(const std::vector<string>& chip_ids) {do sth} Cases that use const reference: "All parameters passed by reference must be labeled const." This rule means thatmutableparameter...
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 ...
Syntax aside, passing a std::array to a function is conceptually simple -- pass it by (const) reference. But what if we have a function that needs to return a std::array? Things are a little more complicated. Unlike std::vector, std::array is not move-capable, so returning a std:...

Of course, I could program second_function in a way that the multiple outputs would be compressed in a vector: 테마복사 function [a]=second_function(x,y,z) a(1)=...; a(2)=...; a(3)=...; But that adds further complications to the rest of my code. I have to clarify...
