4.3 Do not use filenames that already exist in /user/include or any predefined header file name

Brackets position

1. Round brackets detached from the if word and curly brakets on a new line

if (integer % i == 0)
{
    *body *
}

2. Curly brakets on a new line

class Example
{
    *body *
}

3. Round brackets attached to the name of the function/method and curly brakets on a new line

void getExample(int value)
{
    *body *
}
