An integer I pass as an argument becomes a method

Question

I am trying to write a function. Here is the code.

def get_sum(a,b)

  if a == b do

    return a

    end

  else

    total = 0

    for num in a...b

      total += num

    end

    return total

  end

end

I get this error:

undefined method `b' for main:Object (NoMethodError)

Can anyone tell me why I get this?

Answer 1

No do for ifs

if a == b
  return a
end

Note that you can do the same thing so

def get_sum(a, b)
  return a if a == b
  (a...b).inject(:+)
end
