1,222 PointsProblem 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()

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
