I am using the ruby array splat like this:

array = *1,2,3 
Output = [1, 2, 3] 
count = 10 #Initializing count

Question: I want the array to be continued till the count = 10 when I try this it doesn't work array = *1,..,count

Expected Output: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

Is there any possible way to succeed with this way of approach.

Your question is not clear. What are 2 and 3 doing? –  sawa Jun 4 '13 at 11:19
    
Question Edited, I was just showing what I tried first. Basically I was expecting the output to be till count = 10. –  Mark V Jun 4 '13 at 11:25

You will have to do it this way:

array = [*1..count]

count = 10
*(1..count) # => [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

You can simply use Kernel#Array:

Array(1..count)
=> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

I Like Kernel#Hash and Kernel#Array. so +1. –  Arup Rakshit Jun 4 '13 at 11:34

(1..count).to_a, or just (1..count) if you need Enumerable object but not explicitly Array.

count = 10
count.times.map(&:next)
#=> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
