I don't know why there are two constructors that are the same.

08	  TString(const char *pText = 0); // default ctor
09	  TString(const char *pText = 0);

Mainly, there are two types of strings C++ strings and C strings. C strings use character arrays with a null character to terminate the string. Character Sequences


It is useful sometimes to use a pointer to point to this array.

char *pStr

If the pointer equals 0, which is not a valid memory address, then you are to create an empty string.

Hi, here, I've changed the variable names in the second section, and moved gotoxy and printf out of the if sections, and just changed y by 1 instead of four, as previously noted.

  right = 0;
  right_limit = 1;

  down = 0;
  down_limit = 1;

  left = 0;
  left_limit = 1;

  up = 0;
  up_limit = 1;

  for(i=0; i < count; i++)
  {
    gotoxy(x,y);
    printf("%d", number_list[i]);
    /* delay(500); */

    if(right < right_limit)
    {
      x+=4;
      right++;
    }
    else if (down < down_limit)
    {
       y++;
       down++;
    }
    else if(left < left_limit)
    {
       x-=4;
       left++;
    }
    else if (up < up_limit)
    {
      y--;
      up++;
      if(up == up_limit)
      {
        right = down = left = up = 0;
        right_limit += 1;
        down_limit  += 1;
        left_limit  += 1;
        up_limit    += 1;
      }
    }
  }

This test is added because it is clear that the values should only be reset when up is finished.

      if(up == up_limit)
      {

      }

The function Server_ListenForConnections() is in a separate thread but can access the global variables.

So socket would be used for every thread.

I would think about using a mutex around the section lines 36-42, the nextID get and increment.


Don't know if this will be of any use.

The read set parameter will tell you if you can receive data without being blocked.

if (FD_ISSET(s, &fdread)) {
//recv(/*stuff*/);
}

The write set parameter will tell you if you can send data without being blocked.

if (FD_ISSET(s, &fdwrite)) {
//send(/*stuff*/);
}

Hi, firstly, I would look at sending the null character at the end the string as well as the string.
