How can I get the result of this equation

Ruby
1

I have written this a script like this:

values = [10, 20, 30].each {|value| value + (value * 10)}

puts value

In this case, I get:
undefined local variable or method `value’ for main:Object (NameError)

I’m trying to see the result of the equation value + (value * 10)

What should I do?

Thanks.

Ali,

I suspect the example you’re trying was actually printing out
values(…s! plural NOT value)

this would then make sense as a demonstration that the ‘each’ loop did
not
alter the array

more conclusively (using =)

array = [10,20,30]
array.each {|number| number = (number * 10)}
puts array

[10,20,30]
i.e. not [100,200,300]!
