// Declare and initialize variables.
double numStars;

double averageStars; // average star rating.
double totalStars = 0;
int numPatrons = 0;
// total of star ratings.
// keep track of number of patrons
// This is the work done in the housekeeping() function
// Get input.
cout << "Enter rating for featured movie: ";
cin >> numStars;
// This is the work done in the detailLoop() function
