Fair enough. However, Arryn was suggesting that your example was not analogous because the calls were in seperate statements (tho' to be fair, she used the term "lines", so the confusion is understandable).

Here's where those examples came from:

Originally posted by Arryn:
[qb]The problem comes in that the compiler's optimization will substitute the same call to the random number function for both die rolls. It won't make the two rand() calls the coders intend. What it does is make one call and plug the same value into both places. The optimizer does not know that in this circumstance, two calls to the same function do not return the same value.

And in all 3 cases f shall be called twice:

code:

---

  f(); f();



  f(), f();

  

  f()+f()

Edit: Fixed quotations. Again.
P.S. I want real forum/client
