vector add code example

Example 1: insert at position in vector c++

// where v is the vector to insert, i is
// the position, and value is the value

v.insert(v.begin() + i, v2[i])

Example 2: 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;
}
