为什么我的代码不会打开我提供的任何文件？

Question

出于某种原因，我试图提供代码的每个文件都说它不存在。我已经制作了几个文件来尝试并提供它，但没有一个工作。那么我做错了什么或是别的什么？

//Program will read in a list of movies with ratings from a file supplied 
//by the user and then ask the user what rating they would like to see. 
//Then it will give the user the option of seeing all the movies with 
//that rating or a random movie with that rating.
