how to insert values in vector\ code example

Example 1: inserting at start in vector c++

// Inserting at start
vector_name.insert(vector_name.begin(), element_to_be_inserted);

// Inserting after xth element
vector_name.insert(vector_name.begin()+(x-1), element_to_be_inserted);

// Inserting at last
vector_name.push_back(element_to_be_inserted);

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;
}
