how to show all integers of an array in ruby?

Question

I\'m new for ruby. Trying to get all numbers in an array with an method.

x = [1..10]

expected result.

=> [1,2,3,4,5,6,7,         


        

Answer 1

When you type [1..10], what you actually have is an Array containing a single Range object. If you want an array of FixNums, you actually drop the []s and call to_a on the range itself:

irb(main):006:0> x = (1..10).to_a
=> [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

Answer 2

you want to display it?

# This dumps the object to console

x = (1..10).to_a
puts x.inspect

# This prints items individually...

x = (1..10).to_a
x.each do |num|
    puts num
end

# This prints only numbers....

x = (1..10).to_a
x.each do |num|
    if num.is_a?(Integer)
        puts num
    end
end
