c++ merge vectors code example
Example 1: c++ vector combine two vectors
vector1.insert(vector1.end(), vector2.begin(), vector2.end());
Example 2: 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
Example 3: how to concatenate vectors in c++
vector1.insert( vector1.end(), vector2.begin(), vector2.end() );
Example 4: how to append two vectors in c++
std::vector<int> AB = A;
AB.insert(AB.end(), B.begin(), B.end());
