C++ 2 Ruby

Jed Kowalski

Greetings Ruby fans :)
From a couple of months I've been learning C++ but after I found out
about Ruby... it's just GREAT!
Right now im at a beginner level, trying to convert some simplier code
to Ruby (it's easier for me to learn this way)
Can somebody please help me a little? ;>
Ofcourse a working example would be also nice ;)

BTW sorry for my English...

You might have better luck asking for help with specific sections of
code, rather than asking us to rewrite a whole program. Try doing a
best-guest translation to Ruby on your own, and asking about the parts
you have trouble with.

ok so, here's the first problem:
def initialize (cen, ile, nn)
@price=cen
@amount=ile
@name=nn
@bought=0
end


def change(x)
amount--
bought++
return x-price //WHATS WRONG HERE?
end

and I get:

gut.rb:13: void value expression
return x-cena
^
gut.rb:13: syntax error, unexpected tIDENTIFIER, expecting kEND
return x-cena

I think a google search for "Instance Variables" should enlighten you :)

Well, if you want to refer to the @amount, @bought, and @price instance
variables in the change() method you have to use the correct names. Also
Ruby doesn't have the -- and ++ methods.

def change(x)
@amount -= 1
@bought += 1
return x - @price
end

Jed, you could do this:

class MyClass # my most creative invention of a class name
attr_accessor :price,:amount,:name,:bought # creates ways to get/set @price,@amount,... from MyClass

def initialize (cen, ile, nn)
@price=cen
@amount=ile
@name=nn
@bought=0
end
def change(x)
@amount-=1
@bought+=1
x-self.price
end
end

cen=500
ile=400
nn=4
obj=MyClass.new(cen,ile,nn)
p obj.change(1) # -499 =1-500

Jed,

if you ask for a variable using 'gets', this gives you a String.
So you have to write

mystring=gets
case mystring
when '1' # instead of when 1
# ....

I would love to be able to speak Polish ... it's amazing that people who can still ask questions
about anything :)

Best regards,

Axel

Jed,

you don't have an accessor for the instance variable pricea .
It's better not to use global variables (starting with $), also, but
instance variables (starting with @):

class Drink
:attr_accessor :pricea, #...
def initialize (cen, ile, nn)
@price=cen
@ammount=ile
@name=nn
@bought=0
end
end

If you define a function 'pricea()', then you need to call it as
obj.pricea() also, not as obj.pricea ... but in Ruby, people
generally don't use the first form.

Concerning usage of classes, you might find this enlightening:

(and of course, the whole tutorial, not just chapter 9).

Best regards,

how can I print a string and a variable in one line ?
i.e.

drinks.namea()
puts ": ", drinks.buy()


the output will be:

Sprite
:
0

and I would like to have:
Sprite: 0
