Forum:"Negating attack" questions

Heya, I just wanted to know a rule about Negating an attack. If an attack is negated, does that mean it's like the monster never attacked? Here's a few problems I ran into:

1: I have Red Dragon Archfiend and Dark Resonator. Dark Resonator declares an attack, but opponent plays Negate Attack. I declared an attack with Dark Resonator, but it was negated, and "technically" never happened (right?). So would Red Dragon Archfiend destroy my Resonator at the end phase?

2: My opponent plays Mythical Beast Cerberus, a monster card that gains spell counters everytime a spell is played, and he gains atk points equal to the number of spell counters he has x500. And when he attacks or is attacked, he loses his spell counters. So he declares an attack, and I activate Scrap-Iron Scarcrow to negate his attack. Since his attack was negated, would he lose his spell counters after the battle?

Thanks :) ~ElectroBlade
