Write the definition of a function named fileWord that receives a string argument that is the name of a file containing words.
The first time the function is called, it returns the first word of the file whose name it was passed. The second time the function is called, it returns the second, word of the file whose name it was passed (which could be a different file than was passed the first time). The third time, it returns the third word in the file whose name it was just passed, and so on.
My assumption it requires static variable that would remember how many times function was called. This is what I came up with, but on second call (according to codelab) it returns wrong value. Appreciate any advice.
