Summary
In this lab, you write a while loop that uses a sentinel
value to control a loop in a C++ program that has been
provided. You also write the statements that make up
the body of the loop.
The source code file already contains the necessary
variable declarations and output statements. Each
theater patron enters a value from 0 to 4 indicating
the number of stars the patron awards to the Guide's
featured movie of the week. The program executes
continuously until the theater manager enters a
1-
1.
negative number to quit. At the end of the program,
you should display the average star rating for the
16

movie.
