The layout of braces

[WhiteCube]

This is a typical example of the kind of code I see online.

  if (n == 0 || n == 1) {
    isPrime = 0;
  }
  else {
    for(i = 2; i <= n/2; ++i) {
      if(n % i == 0) {
        isPrime = 0;
        break;
      }
    }
  }

11 lines, and none of the open braces line up with closing braces.

I would do it like this...

  if (n == 0 || n == 1)
  { isPrime = 0;
  }
  else
  { for(i = 2; i <= n/2; ++i)
    { if(n % i == 0)
      { isPrime = 0;
        break;
  } } }

9 lines, exact same indenting, and every brace lines up.

Okay, I'm cheating on the last 3 braces, the order is wrong, but since they are the same character, I don't see a problem.

Check the code notation from C#

if (n == 0 || n == 1)
{
    isPrime = 0;
}
else
{
    for(i = 2; i <= n/2; ++i)
    {
        if(n % i == 0)
        {
            isPrime = 0;
            break;
        }
    }
}

IMO, writing code across multiple lines (e.g., splitting longer expressions into smaller parts or splitting blocks of code) is not a problem for the compiler and does not affect its performance. The compiler processes the code in such a way that whitespace characters (including newlines) are usually ignored unless they have a specific meaning in a given programming language (e.g., Python, where indentation matters).

When there's too much white space, I have to scroll the screen from the start of the loop/if to the end.

When the opening brace is more than a screen height from the closing brace, it makes a program hard to read, for a human.
