Curly brackets

Question

So I was trying to figure some stuff out about these two different ways to write curly brackets. Here's an example:

1)
if (condition) {

}

2)
if (condition)
{

}

So in the first example you write the open brace after the condition and in the second example you write the open brace under the condition, so my questions were:

1.Is there a name for these two ways of writing the curly brackets?
2.Which way is more used in professional programming?

Answer 1

1) I never heard anything about names of these ways, everyone just calls them "opening on the same/next line".
2) It is a personal preference. You should use the one you like. Personally I always open the bracket on the same line

Answer 2

No there is no name of these ways. You can write in any ways. I mostly prefer this

if(condition) {

}

because we can save 1 extra line. So if there are many conditions then we can save more extra line..

If there is a single statement then I don't like to use curly braces. I just write

if (condition) //statement
