Plz Correct this code................

#include<iostream>
#include<vector>
#include "mpi.h"

using namespace std;

int main(int argc, char *argv[])
{
        MPI::Status status;
        MPI::Init();
        int myrank = MPI::COMM_WORLD.Get_rank();
        int numprocs = MPI::COMM_WORLD.Get_size();
        vector<int>  ourvector(2);
        if(myrank == 0){

        ourvector[0] = 98;

//      cout << "The max number the vector can hold is : " <<
ourvector.max_size();


//      cout << "\nourvector has : " << ourvector.capacity() << " elements
in it";

        ourvector.push_back(99);


//      cout << "\nNow ourvector has : " << ourvector.size() << " elements
in it";

//      cout << "\nThe Value of the first vector element is : " <<
ourvector[0];


//      cout << "\nThe Value of our second vector element is : " <<
ourvector.at(1) << endl;

         MPI::COMM_WORLD.Send(&ourvector[0],2,MPI::INT, 1, 1);
        // MPI::COMM_WORLD.Send(&ourvector[1],1,MPI::INT, 1, 1);
        }
        else{
        ourvector.reserve(2);
       MPI::COMM_WORLD.Recv(&ourvector[0],2, MPI::INT,0,1);
        // MPI::COMM_WORLD.Recv(&ourvector[1],1, MPI::INT,0,1);

        //ourvector.pop_back();


        cout << "ourvector now has : " << ourvector.capacity() << "
elements" <<  endl;
      cout << "\nNow ourvector has 1st : " << ourvector[0];
        cout << "\nNow ourvector has 2nd : " << ourvector[1]<< endl;
//      cout << "Our fisrt element in ourvector is : " << ourvector.front()
<< endl;


        ourvector.resize(9);

        ourvector.at(8)  = 99;

//      cout << "Our last element in ourvect is : " << ourvector.back() <<
endl;

//      cout << "ourvector now holds : " << ourvector.size() << " elements"
<< endl;
        }
      MPI::Finalize();
        return 0;
} <http://trac.guake-terminal.org/files/>


Now MY output is
$ mpirun -np 2 ./vec.out
ourvector now has : 2 elements

Now ourvector has 1st : 98
Now ourvector has 2nd :0

I want output like <http://trac.guake-terminal.org/files/>
$ mpirun -np 2 ./vec.out
ourvector now has : 2 elements

Now ourvector has 1st : 98
Now ourvector has 2nd :99
