vector's copy constructor

  
 

#include <iostream>
using std::cout;
using std::cin;
using std::endl;

#include <iomanip>
using std::setw;

#include <vector>
using std::vector;

int main()
{
   vector< int > integers1( 7 ); // 7-element vector< int >
   vector< int > integers2( 10 ); // 10-element vector< int >

   size_t i;
   
   for ( i = 0; i < integers1.size(); i++ ){
      cout << integers1[ i ];
   }
   for ( i = 0; i < integers2.size(); i++ ){
      cout << integers2[ i ];
   }

   vector< int > integers3( integers1 ); // copy constructor

   cout << integers3.size() << endl;
   for ( i = 0; i < integers3.size(); i++ ){
      cout << integers3[ i ];
   }

   return 0;
