Exercise 10

Using the code from Exercise 9, classify each variable name as either global or local. For our purposes here, you may assume that the code from Exercise 9 is the entire program.

Solution

Global Variables: multiply, getNumber, left, right, console, parseFloat, question.
Local Variables: left, right, product, prompt

Function names are global variables unless those functions are defined as an object property or nested inside another function. Thus, multiply, getNumber, console, parseFloat, and question are all global variables in this program. In addition, function parameters and variables declared inside a function are always local variables. Thus, left, right, product, and prompt are all local variables.

In the next exercise, we'll see why left and right are both global and local variables.

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
