combine two vectors c++
vector<int> v1 = {1, 2, 3}; vector<int> v2 = {4, 5, 6}; copy(v1.begin(), v1.end(),back_inserter(v2)); // v2 now contains 4 5 6 1 2 3
concatenate two vectors c++
#include <vector> // vector #include <iostream> // output using namespace std; int main() { // two vectors to concatenate vector<int> A = {1,3,5,7}; vector<int> B = {2,4,6,8}; // vector that will hold the combined values of A and B std::vector<int> AB = A; AB.insert(AB.end(), B.begin(), B.end()); // output for (auto i : AB) { cout << i << ' '; } }

joining two vectors in c++
// my linkedin : https://www.linkedin.com/in/vaalarivan-prasanna-3a07bb203/ vector<int> AB; AB.reserve(A.size() + B.size()); // preallocate memory AB.insert(AB.end(), A.begin(), A.end()); AB.insert(AB.end(), B.begin(), B.end()); //eg : A = {4, 1}, B = {2, 5} //after the 2 insert operations, AB = {4, 1, 2, 5}
