// 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?
// we have 6 variable declarations.
// b) How many function calls are there?
// here we have only one which is console.log().
// c) Using documentation, explain what the expression movieLength % 60 represents
// https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Arithmetic_Operators
// Remainder operator (%), returns the leftover when one operand divided by the other operand.
// movieLength % 60 expression represents the remaining seconds.
// d) Interpret line 4, what does the expression assigned to totalMinutes mean?
// that expression turns the seconds into minutes.
// e) What do you think the variable result represents? Can you think of a better name for this variable?
// the result variable represents the movie length in Hour, minutes and seconds.
// a better name can be "movieLength".
// f) Try experimenting with different values of movieLength. Will this code work for all values of movieLength? Explain your answer
// as I changed the value of the movieLength the results has changed too.It means this code works with any value.
