C++/Java/C modes

[David Rasmussen <david.rasmussen@gmx.net>]

Two questions:

1) How do change it so that when I press enter on a line, the cursor is 
already at the natural indentation point with spaces inserted before. 
Example:

int main()
{
   std::cout << "Hello, world!" << std::endl; <pressing enter>
<cursor is normally here>
   <I want it here>

2) How can I change the auto indentation style so that instead of

   if (whatever) <pressing enter>
<pressing tab, which shouldn't be necesary, if I get a good answer to 
question 1>
     <cursor is here!>
   <I want it here>

I guess the last question is about using the

   if (whatever) {
     blabla
   }

style. I (want to) use the

   if (whatever)
   {
     blabla
   }

style.

Help? Maybe I should just give in and go with the flow and use the short 
style.
