How to combine two integer vector

Question

I'm wondering how to combine two integer like this

vector <int>  A = {3,4,5};
vector <int>  B = {100,102,103};

and then can we have a fast way or a funtion that can help to attach the vector B to vector A and vector A then look like this :

A = { 3,4,5,100,102,103}

If you just want to append `B` to `A` and not want `A` to be sorted at the end, you can use STL `std::copy` algorithm. — srt1104, Oct 27 '19 at 04:56

You can do this using insert of c++

A.insert(A.end(), B.begin(), B.end());

Use std::vector::insert:

std::vector<int> A { 3, 4, 5 };
std::vector<int> B { 100, 102, 103 };
A.insert(A.end(), B.begin(), B.end());
