This is a repost of my own message to make things more clear.
Here is an example:

class Object {
protected:
char some_stuff[2000];
int x, y;
public:
Object (void) {}
Object (int nx, int ny) {x = nx; y=ny;}
//the constructor is doing much more but I think it's irrelevelant.
...
};

my_obj Object;

void InitObj(int x, int y)
{
my_obj = Object(x, y);
....
}

main()
{
int x,y;
while (1==1) {
   scanf("%d%d", &x, &y);
   InitObj(x, y);
}
...
}

This is only an example so it might not be correct. It's only to
illustrate what I mean.
Thanks.
