The problem with a lot of the "Welcome to C++ books" are that large chunks of time are spent repeating material from books I already own, or lectures I've already sat in. I'm just trying to get my money's worth, not flaunt knowledge.Gaspode_T said:

Yeah right. Still, even when the rocket and circle is perfectly aligned against each other, the rocket bounces to the side. It should bounce straight back where it came from.Lasthope106 said:
