// For the piece of code above, read the code and then answer the following questions
// a) How many variable declarations are there in this program?
// 6 variable declarations.
// b) How many function calls are there?
// 0 function calls.
// c) Using documentation, explain what the expression movieLength % 60 represents
// https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Arithmetic_Operators
// The expression returns the remainder left over when movieLength is divided by 60. In this case.
// d) Interpret line 4, what does the expression assigned to totalMinutes mean?
// The expression on line 4 calculates the length of the movie in minutes.
// e) What do you think the variable result represents? Can you think of a better name for this variable?
// Result represents the movie length formatted as hours:minutes:seconds. A better name could be
// formattedMovieLength.
// f) Try experimenting with different values of movieLength. Will this code work for all values of movieLength? Explain your answer
// As long as movieLength is a non-negative integer representing seconds, the code will work.
