Re: Beginner question: how to free space of vector?

Hi,

I have a problem with using vector to transfer new data into a class.
Running valgrind on the following program gives
lost memory, but I'm not sure why.

Help appreciated,

Matthias

#include <vector>
#include <iostream>

typedef std::vector<int> TInt;
class mem
{
     TInt demo;

public:
     void set_mem(TInt &line)
     {
          std::cout << demo.capacity();
               // I believe the problem is here: what was contained in
demo is now lost
               // but could someone enlighten me pls?
          demo = line;

     }

     mem()
     {
          for (int j = 0; j < 5; j++)
          {

               demo.push_back(j);
          }
     }

     ~mem()
     {
                // I already read that clear doesn't force vector to
free its space, how can I achieve
                // this? resize() doesn't seem to have any effect
either...
          demo.clear();
     }
};

int main()
{
     mem* test;
     TInt d;
     for (int i = 0; i < 10; i++)
          d.push_back(i);

     test = new mem();
     test->set_mem(d);

}
