[Lua] Sentence Generator

This one was pretty tough for me. Not necessarily the coding concepts, but the grammar concepts. I actually failed my English II class in high school and was never really good in English class. However this code demonstrates how to create a complex sentence from various words that are stored in arrays.

Code:

---

-- Create the random seed for the random function
math.randomseed(os.time())

-- Our grammar arrays
articles = {"the", "a", "one", "some"}
nouns = {"baby", "boy", "girl", "child", "man", "woman", "dog", "cat", "town", "car"}
verbs = {"drove", "jumped", "ran", "walked", "skipped", "joke"}
prepositions = {"to", "from", "over", "under", "on", "about"}


while true do

        -- Tell the user to press enter
        io.write("Press enter to generate a sentence.")
        io.read()

        -- Set article1 to some random number
        article1 = math.random(1, table.getn(articles))

        -- Do the same for article two, but don't allow for duplicates
        repeat
                article2 = math.random(1, table.getn(articles))
        until article1 ~= article2

        -- Set noun1 to some random number
        noun1 = math.random(1, table.getn(nouns))

        -- Do the same for noun two, but don't allow for duplicates
        repeat
                noun2 = math.random(1, table.getn(nouns))
        until noun1 ~= noun2

        -- Set the verb to some random number
        verb = math.random(1, table.getn(verbs))

        -- Set the preposition to some random number
        preposition = math.random(1, table.getn(prepositions))

        --Print out our random sentence by getting string that is associated with the array
        io.write(articles[article1] .. " " .. nouns[noun1] .. " " .. verbs[verb] .. " " .. prepositions[preposition] .. " " .. articles[article2] .. " " .. nouns[noun2] .. "\n\n")

end
