Re: Decks and Dice

Of course, the code I posted above will require that the compiler emit separate code for each N that you use in your program, rather than in the non-template version that uses a member variable for sides. Since the typical game will not have more than about a half-dozen different N's, this is not likely to be a concern.

With a simple program that does nothing but instantiate an instance of Dice for N=4,6,8,10,12,20, and call each member function once, I measured the code bloat as shown below (g++ 4.0).
Without compiler optimization (other than default):

Code:

-rwxr-xr-x 1 matthew matthew  7228 2006-04-12 10:41 testdice_mainonly
-rwxr-xr-x 1 matthew matthew  8436 2006-04-12 10:55 testdice_notemplate
-rwxr-xr-x 1 matthew matthew 10926 2006-04-12 10:55 testdice_template

With -O2 compiler optimizations:

Code:

-rwxr-xr-x 1 matthew matthew  7212 2006-04-12 10:41 testdice_mainonly
-rwxr-xr-x 1 matthew matthew  8079 2006-04-12 10:55 testdice_notemplate
-rwxr-xr-x 1 matthew matthew  9245 2006-04-12 10:55 testdice_template

P.S. I forgot to mention something again. I did not use the RNG class, but simply called the rand() function for my test. It is just meant to give a rough idea anyhow.

Thanks QED. I'm out of town working until this weekend but with davis' and your suggestions I am looking forward to playing with this when I get home. Your tips jive with the lines I had been thinking along.

We both need to modify our code such that Dice<0> isn't allowed...

Of course, Dice<1> is of little use too, huh?
