Exercise 9

Which of the following names don't satisfy the style guidelines for naming variables, functions, or constants?

Name
`index`
`CatName`
`snake_case`
`lazyDog`
`quick_Fox`
`1stCharacter`
`operand2`
`BIG_NUMBER`

Solution

Unacceptable names: snake_case and quick_Fox contain underscores; underscores are permitted in constant names, but these aren't constant names since they use lowercase letters. 1stCharacter isn't valid at all: names may not begin with a digit.

Code Blocks

You can write code blocks using three backticks (```) followed by the language you want to show. For instance, if you wanted to write a Ruby code block you would write:

```ruby
class Foo
end
```

class Foo
end

You can also leave out the language identifier, doing this will make it so your code isn't highlighted at all, and all text will be white with no coloring.

```
class Bar
end
```

class Bar
end

Highlighting

You may highlight lines within your code blocks. This is a different type of highlighting, and isn't related to how the code within your code block may be colored depending on the language identifier used.
To highlight one or more lines of code, add # highlight on a separate line just before the first line you wish to highlight. To end highlighting, add # endhighlight on a separate line immediately after the last line you wish to highlight.

```ruby
def say_hello_world
# highlight
  puts 'Hello World!!!'
# endhighlight
end
```

def say_hello_world
# highlight
  puts 'Hello World!!!'
# endhighlight
end
