    Exclamation Help with game, just starting


    My boss told me to pick up a ruby book and start figuring, so he gave me this assignment to write a small game:

    He sent me an email with:

    > race.rb
    > construct an array of cars,
    > accept entry of two cars,
    > race the two cars,
    > determine and display a winner
    >
    > example:
    >
    > #each car is [name, horsepower, weight] cars = [
    > ['mustang', 300, 3480 ],
    > ['camaro', 400, 3780 ],
    > ['s2000', 237, 2864 ],
    > ['350z', 287, 3288 ]
    > ]
    >
    > run it giving two car names on the command line, example:
    > ruby race.rb mustang camaro
    >
    > Use ARGV[0] as the name of the first car, and ARGV[1] as the name of
    > the second car, as follows:
    > name1 = ARGV[0] || 'mustang'
    > name2 = ARGV[1] || 'camaro'
    >
    > Locate both cars in the array, compare their performance numbers, and
    > pick a winner.
    >
    >

    So how on earth do i do this???? Please help!!

    The only thing not spelled out in that description is the equation of speed as it relates to weight and horsepower. What exactly have you tried?

    I should warn you that as an employee you are expected to think - that is what a portion of your paycheck is intended to represent. If I had given you this problem to work out I would have a bank of questions intended to determine if you understood what you just did. I would want to know what roadblocks you ran into (however trivial) and how you overcame them. You farming an answer sets you up for a hard failure in that respect. Maybe your employer wont care how you got your answer - I wouldn't bank on that, however.
    True happiness is not getting what you want, it's wanting what you've already got.

    He's already given you most of the code.

    ruby Code:
     
    # race.rb
     
    #each car is [name, horsepower, weight]  
    cars = [  
      ['mustang', 300, 3480 ],  
      ['camaro', 400, 3780 ],  
      ['s2000', 237, 2864 ],  
      ['350z', 287, 3288 ]  
    ]  
     
    name1 = ARGV[0] || 'mustang'  
    name2 = ARGV[1] || 'camaro'


    That's a pretty good start. The next step is to match the correct car with the name

    ruby Code:
    car1 = *your code here*  
    ...


    I'd recommend learning about accessing Array elements with [] and then look into the detect method on the Array class.

    Once that's done, figure out how to compare the speed.

    I was able to create a working version with just a few lines of code beyond what he gave you.
