c++ copy vector code example

Example 1: store vector in another vector c++

Input:
    vector<int> v1{ 10, 20, 30, 40, 50 };
    vector<int> v2{ 100, 200, 300, 400 };

    //appending elements of vector v2 to vector v1
    v1.insert(v1.end(), v2.begin(), v2.end());

    Output:
    v1: 10 20 30 40 50 100 200 300 400
    v2: 100 200 300 400

Example 2: copy a part of a vector in another in c++

// Copying vector by copy function 
copy(vect1.begin(), vect1.end(), back_inserter(vect2));

Example 3: copy file to vector c++

//Read file to the end
while(inFile.read(reinterpret_cast<char*>(&temp), sizeof(temp)))
{
    //Store each int in the vector
    myVector.push_back(temp);
}
