add two vectors c++ code example

Example 1: vector concat c++

vector1.insert( vector1.end(), vector2.begin(), vector2.end() );

Example 2: c++ vector combine two vectors

vector1.insert(vector1.end(), vector2.begin(), vector2.end());

Example 3: 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 4: how to concatenate vectors in c++

vector1.insert( vector1.end(), vector2.begin(), vector2.end() );
