push vector c++ code example

Example 1: how to append one vector to another c++

vector<int> a;
vector<int> b;
// Appending the integers of b to the end of a 
a.insert(a.end(), b.begin(), b.end());

Example 2: adding element in vector c++

vector_name.push_back(element_to_be_added);

Example 3: add to vector c++

// vector::push_back
#include <iostream>
#include <vector>

int main ()
{
  std::vector<int> myvector;
  int myint;

  std::cout << "Please enter some integers (enter 0 to end):\n";

  do {
    std::cin >> myint;
    myvector.push_back (myint);
  } while (myint);

  std::cout << "myvector stores " << int(myvector.size()) << " numbers.\n";

  return 0;
}

Example 4: java vector push_back

// push_back equivalent
ArrayList<int> a = new ArrayList<int>();
a.add(2);             // Add element to the ArrayList.
a.add(4);

// pop_back equivalent.
a.remove(a.size()-1); // Remove the last element from the ArrayList.
