Problem with While Loop Code

Hi,

Not sure what's wrong with my loop code. Any ideas?

i = 0 def i_loop(i) while i < 5 i = i + 1 end end i_loop(i)

This also seems like it should work but doesn't:

def i_loop() i = 0 while i < 5 i = i + 1 end end

i_loop()

The loop seems to be working on my end. 

def i_loop() 
    i = 0 
    while i < 5 
        i = i + 1 
    end 
end

i_loop

You may not see anything because you're not printing or returning anything. If we added a puts statement to print out i at every iteration, you would be able to see the loop in action. 

def i_loop() 
    i = 0 
    while i < 5 
        i += 1 
        puts i
    end 
end

i_loop
