Need to get() in a vector containing objects

[Jonas Wingren]

Hi!
I need to use the Get() functions I wrote for a class. However I use a vector to create and store the objects of that class(need alot of them). So, I wonder how do I do this?

#include "Map.h"
#include "global.cpp"
void Map::Create()
{
     cout << "\n\nCreating the Map\n\n";
     int a = 0;
     while(a < NUM_CELLS)
     {
                       m_Cells.push_back(a);
                       ++a;
     }
     cout << "\n\nSuccesfully created the Map... puuh!\n\n";
     cout << "It contains " << a << " cells\n\n";
     return;
}

void Map::Load()
{
     cout << "\n\nLoading the Map settings...\n\n";
     ifstream Mapfile;
     string line;
     int a=0;
     Mapfile.open ("Cells.txt");
     if (Mapfile.fail())        // this checks if it loads right?
     {
        cout << "Failed load"; 
        return;
        }
     
     else{
          vector<Cell>::iterator iter = m_Cells.begin(); 
          while(getline(Mapfile,line))
          {
                    stringstream(line) >> a;
                    iter->Setpop(a);
                    getline(Mapfile,line);
                    iter->Setbuildings(line);
                    ++iter;
          }
     
     }
     cout << "Load successful\n\n";
     return;
}

void Map::Save()
{
     cout << "\n\nSaving the Map... This might take a while.\n\n";
     ofstream Mapfile;
     string line;
     int a=0;
     Mapfile.open("Cells.txt");
     if (Mapfile.fail())       //checks if it loads correctly     
     {
        cout << "Failed Save"; 
        return;
        }
     
     else{
          vector<Cell>::iterator iter = m_Cells.begin();
          while(a < NUM_CELLS)
          {
                  Mapfile << iter->Getpop() << endl;
                  Mapfile << iter->Getbuildings() << endl;
                  ++a;
                                       
          }
     
     }
     cout << "Save successful\n\n";
     return;
}

#include "Cell.h" 
    
class Map
{
      public:
             Map::Map(int spaces = 1) { m_Cells.reserve(spaces); }
             // get
             int Getpop(int);
             string Getbuildings(int);
             //operations
             void Create();
             void Save();
             void Load();
             void Access();
             
             
      private:
              vector<Cell> m_Cells;
};

any suggestions on improvement in the code are welcome.
