C++/Java/C modes

[David Rasmussen]

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.
