Why does the rand() return always the same number?

Question

I am using

rand(200)

in my Rails application. When I run it in console it always returns random number, but if I use it in appl

Answer 1

rand(200) is run once and that value is assigned to your index variable. So 'index' will always be that number.

If you want index to change, you will need to continually run rand on it.

Here's a simple way to do that:

def randomIndex(num)
  index = rand(num)
  return index
end

randomIndex(200)
=> // this value will change
