Use indexer to add elements to a deque


#include <iostream>
#include <cassert>
#include <algorithm>
#include <vector>
#include <deque>
using namespace std;

int main()
{

  deque<int>  deque1(5);

  for (int i = 0; i < 5; ++i)
    deque1 = i + 5;

  deque<int>::iterator pos;

  for (pos=deque1.begin(); pos!=deque1.end(); ++pos) {
        cout << *pos << ' ';
  }

  return 0;
}

/*
5 6 7 8 9
*/       

Use subscript operator to modify element at location 1


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

#include <deque>     // deque class-template definition
#include <algorithm> // copy algorithm
#include <iterator>  // ostream_iterator

int main()
{
   std::deque< double > values; // create deque of doubles
   std::ostream_iterator< double > output( cout, " " );

   // insert elements in values
   values.push_front( 2.2 );
   values.push_front( 3.5 );
   values.push_back( 1.1 );

   cout << "values contains: ";
   std::copy( values.begin(), values.end(), output );

   // use subscript operator to modify element at location 1
   values[ 1 ] = 5.4;
   cout << "\nAfter values[ 1 ] = 5.4, values contains: ";
   std::copy( values.begin(), values.end(), output );

   cout << endl;
   return 0;
}

/*
values contains: 3.5 2.2 1.1
After values[ 1 ] = 5.4, values contains: 3.5 5.4 1.1

*/

Use subscript operator to obtain elements of values



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

#include <deque>     // deque class-template definition
#include <algorithm> // copy algorithm
#include <iterator>  // ostream_iterator

int main()
{
   std::deque< double > values; // create deque of doubles
   std::ostream_iterator< double > output( cout, " " );

   values.push_front( 2.2 );
   values.push_front( 3.5 );
   values.push_back( 1.1 );

   cout << "values contains: ";
   // use subscript operator to obtain elements of values
   for ( int i = 0; i < values.size(); i++ )
      cout << values[ i ] << ' ';
   cout << endl;
   return 0;
}

/*
values contains: 3.5 2.2 1.1
