c++ - What is the best way to concatenate two vectors? - Stack Overflow

Note boost::join does not copy the two vectors into a new container but generates a pair of iterators (range) that cover the span of both containers. There will be some performance overhead but maybe less that copying all the data to a new container first. Share Improve this answer answered Jul 5, 2010 at 8:55 bradgonesurfing 30.3k 15 110 210 1

c++ - How to concatenate many std::vectors? - Stack Overflow

Concatenating two vectors can be done via insert. For my example I would use this: std::vector<double> BClass::getCoeffs () { std::vector<double> coeffs; std::vector<double> fcoefs; for (int i=0;i<aVector.size ();i++) { fcoefs = aVector [i].getCoeffs (); coeffs.insert (coeffs.end (),fcoefs.begin (),fcoefs.end ()); } return coeffs; }

Concatenate multiple vectors in C++ | Techie Delight

Concatenate multiple vectors in C++ This post will discuss how to concatenate multiple vectors in C++. 1. Using std::vector::insert A simple solution to concatenate the contents of a vector into another vector is using the std::vector::insert member function. It can be used as follows: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 #include <iostream>

How to concatenate multiple vectors in C++ - CodeSpeedy

Concatenation refers to as joining of two or more vectors together in a single vector. Let’s understand this using a simple example:– vector X= {1,2,3,4} vector Y= {5,6,7,8} X concatenate Y = { 1,2,3,4,5,6,7,8} Method 1 : Using std::reverse and std::insert Let’s have a look at the code—> #include <iostream> #include <vector> using namespace std;

C++ Tutorial => Concatenating Vectors

Instead of using the vector's member functions, the functions std::begin() and std::end() can be used:. a.insert(std::end(a), std::begin(b), std::end(b)); This is a more general solution, for example, because b can also be an array. However, also this solution doesn't allow you to append a vector to itself.
