Thread: Login Function??

im getting an error with this piece of code, im sure theres a better way to do it but hey its my first shot at it;

Code:

string Login()
{//function
     
     int x,i,y;
     char Buffer[50], Buffer2[50], Username[50], Password[50];          
     char ch = getch();
     
    do
    {
        system("cls");
                      
        cout << "Login" << endl
             << endl;                                   
             
        cout << "Username       : ";
        cin.getline(Username, 50, '\n');    
        
        cout << endl;           
        cout << "Password       : ";
            
            while (ch != '\r')
            {//while                                                                      
                  i=0;                 
                  ch = getch();
                  Password[i] = ch;   //small loop so only * are displayed instead of actual password
                  cout << '*';
                  i++;
            }//while
            
     ifstream SAM_File("C:\\Documents and Settings\\Dean.Downstairs\\My Documents\\OperationalFiles\\SAMFile.dat");     
     SAM_File.getline(Buffer, 50);
     
     for(x=0; x<50; x++)
     {             
             SAM_File.getline(Buffer[x],x);  //gets set username from .dat file
     }
     
     
     for(y=0; y<50; y++)
     {
              SAM_File.getline(Buffer[y],y);  //gets set password from .dat file
     }
                       
     SAM_File.close();
         
     ch = ' ';         //sets to 0 so its not full
     
     } while(Buffer != Username || Buffer2 != Password);
                 
};//function

thanks for help in advance,
