inserting an element in a vector c++ code example

Example 1: adding element in vector c++

vector_name.push_back(element_to_be_added);

Example 2: vector insert

// inserting into a vector
#include 
#include 

int main ()
{
  std::vector myvector (3,100);
  std::vector::iterator it;

  it = myvector.begin();
  it = myvector.insert ( it , 200 );

  myvector.insert (it,2,300);

  // "it" no longer valid, get a new one:
  it = myvector.begin();

  std::vector anothervector (2,400);
  myvector.insert (it+2,anothervector.begin(),anothervector.end());

  int myarray [] = { 501,502,503 };
  myvector.insert (myvector.begin(), myarray, myarray+3);

  std::cout << "myvector contains:";
  for (it=myvector.begin(); it
