erasing vectors

Code to implementing erasing of vectors

 

----------------------------Code 1 ----------------------------------------------------------

 

# include <iostream>

# include <vector>

# include <algorithm>

 

using namespace std;

 

typedef std::pair<int, vector<int> > int_vec_pair;

typedef std::pair<int, int > int_pair;

typedef std::vector<int_vec_pair>  vec_int_vec_pair;

typedef std::vector<int_pair>      vec_int_pair;

typedef vec_int_vec_pair::iterator vec_int_vec_pair_it;

 

int main()

{

  int const proc_id = 5;  // we have more of these/hardcode 1 for test purposes.

 

  typedef vector<int> VEC_INT;

  VEC_INT size_vec;

  size_vec.reserve(8);

  size_vec.push_back(0x100000);

  size_vec.push_back(0x200000);

  size_vec.push_back(0x300000);

  size_vec.push_back(0x400000);

 

  vec_int_vec_pair v1;

  v1.push_back(std::make_pair(proc_id, size_vec));

  // will be doing push_back on more proc_id with different size_vecs..for

  // now use 1 element.

 

  vec_int_pair v2;

  v2.push_back(std::make_pair(proc_id, 0));

  // ditto.. more proc_ids all zerod out.. for now use 1 element

 

  int bytes_xferred = 0x100000;

 

  {

    v2[0].second = bytes_xferred;

    if (v1[0].first == proc_id)  // pure test purspose. so fix this so the construct is true ..

 

    {

       if (v2[0].second == v1[0].second[0])

       {

          // I would like to erase

          // v1[0].second[0] here...

          // my intent is to ultimately erase all the size_vec elements in vec_int_vec_pair

         cout << " erasing " << endl;

        cout << v1[0].second.size(); // check to see if size is 3.

                                                   // revist this afterperusing text.. how to do this

                   // given vector pair

          v2[0].second = 0;

       }

    }

  }

  return 0;

}
