Assignment 4: Expressions and Conditions: Part 2

  1. [2 pts] Fix the second page from Part 1 so that it displays an appropriate message for the quotient if the user enters the number 0.
  2. [2 pts] Create a page that asks the user for an hour (a number) between 0 and 23 and reports whether the hour corresponds to morning (6-11), afternoon (12-18), or night (18-23 and 0-5).
  3. [2 pts] Create a page that asks the user for their name and their favorite genre (kind) of music, and then does the following:
    • If their favorite style of music is jazz, ask what instrument they prefer. If the answer is saxophone, ask if they prefer soprano, alto, or tenor sax.
    • If their favorite style of music is classical, ask which composer they prefer. If the answer is Mozart, ask which piece is their favorite.
    • Otherwise, ask who is their favorite artist.
    Have your script produce a nice summary of the answers as the content of the page.

Things to think about

  • Conditional statements are the most basic building block of programs that do more than one thing.
  • Understand the role of curly braces ({ and }) in delimiting blocks, especially in if statements.
  • Understand how to use whitespace (indentation) in your programs to improve readability, especially of blocks, but realize that whitespace is almost always not actually meaningful in Javascript (unlike, say, Python).
