Checking each argument in a method?
ruby
Solution
def is_number? *args; args.all?{|a| a.kind_of?(Fixnum)} end
Replace `Fixnum` if you want a different class to match.
Problem
Let's say I have a method that has the following... ``` def is_number?(a,b,c,d) # ... check if the argument is a number end ``` Is it possible to iterate through each argument passed to `is_number?` and do what is within the method? For example... ``` is_number?(1,3,"hello",5) ``` Would go through each argument and if the argument each argument is a number it would return true, but in this case, it would return false due to `"hello"`. I already know how to check if an input is a number, I just want to be able to check numerous arguments all in one method.
