//The file should consist of the name of the album, quantity shipped and price.
// Since we do not know how many CD's have been shipped, keep reading the file
//until all CD's have been read in. Keep track of both the number of different
//CDs as well as the total number of CDs shipped. Your program should determine
//the value of each CD shipped (quantity * price). Create an array to hold this
//value and print out all values in the array.
