c++ - Passing vectors by reference - Stack Overflow

It is possible to have a vector of reference-wrappers a la std::ref, but if you don't know what that is, you probably shouldn't be using it at this point. Share. Improve this answer. Follow answered Nov 1, 2011 at 12:17. Kerrek SB Kerrek SB. 479k 95 95 gold ...

Vector in C++ STL - GeeksforGeeks

Vectors can be passed to a function as arguments just like any other variable in C++. But it is recommended to pass the vector by reference so as to avoid the copying of all elements which can be expensive if the vector is large. Refer to this article to know more - Passing Vector to a Function. Internal Working of Vector

Call by value and call by reference in C++ - Tpoint Tech - Java

We work with large data because call by reference does not make a copy of the data. We have a large object and wish to avoid the overhead of copying this object. Advantages of Call by Value and Call by Reference: There are several advantages of call by value and call by reference in C++. Some main advantages of these functions are as follows:

【C++】vector容器实现 - CSDN博客

vector<vector<int>>它本质上是一个二维动态数组，模版变量可以是任何类型的指针，当然也可以是vector<int>*指针类型。想象 vector<vector<int>> 就像一组可以伸缩的抽屉柜：外层 vector：这是一个大柜子，里面可以放很多抽屉（每个抽屉就是一个 vector<int>）

c++ - Reference vs. pointer - Stack Overflow

vector<int> v(20); v[1] = 5; //The target of the assignment is the return value of operator [] Here the operator [] returns a reference of the element at the specified index in the vector. Had operator [] been designed to return a pointer to the element at the specified index the 2nd line would have to be written like this:-*v[1] = 5

c++ - Pointer to vector vs vector of pointers vs ... - Stack Overflow

And of course the case you mentioned, where you store various subclasses of a base class in the vector, will require pointers. A reference counting smart pointer like boost::shared_ptr will likely be the best choice if your design would otherwise require you to use pointers as vector elements.

vector::push_back conversion from const Type* to type*

You can't do this. Since addFriend promises to not prevent the User from being altered, storing it into a vector of non-const User* would allow anyone with access to the vector to modify the User however they please. Possible solutions: Let addFriend take User* instead of const User*. Even better: use a reference unless you have really good ...

Foreach range iteration over a vector<int> - auto or auto&?

First of all, if you going to modify value use auto&, if not - don't.Because you can accidentally change it. But there may be choice between const auto& and simple auto.I believe that performance isn't issue here, for std::vector<int>.. Why use auto. It's easier to read.
