    Writing a member variable to a text file

    Hi,

    I have an EnemySprite object that has an int member variable called Chromosome. The value of it is "1".

    I'm trying to write that value to a text file, but instead of getting "1" I am getting "1244044", which I presume is the RAM address of the variable.

    I can't figure out why can't I get to the value of the variable.

    Here is a little code example:

    Code:
    void GA::StoreDeadEnemyInfo(Sprite* pEnemySprite) {
    
    ofstream f("Dead_Enemies.txt", ios::app);
       f << pEnemySprite->GetChromosome();
       f << "_";
       f << fitness;
       f << "\n";
    
    }
    Any advice on this is really appreciated. Thanks.

    Code:
    class EnemySprite : public Sprite                                           
    {
      protected:
        int           m_iChromosome;                                
        int           m_iFitness;
      public:                                                                      
        ..........ETC................
        int GetChromosome() {
          return m_iChromosome;                                            
        };
    There's the key bits from the EnemySprite file.

    Well, I don't see anything wrong with it, perhaps it's not really storing a 1 as you think
