For each program, you should turn in the source code and a print-out showing a sample run (print the output window). Follow the guidelines in Section 3.7 for the style of your programs. In addition:

1. Use descriptive names for variables and named constants. In addition, write a brief comment for each variable and named constant describing how it is used.
2. Use uppercase characters for named constants with underscores to separate ``words.'' Use lowercase characters for variables with either underscores or capitalization to separate ``words.''
3. If a formula you use in a statement isn't obvious, comment it. In general, comment any non-obvious statement or statement block.

Documentation will account for 30% of your grade.

1. Write a program which accepts as input a single integer value and outputs:
   • The prime factors of the number, if the number is not prime.
   • The statement ``n: prime,'' if the number, n, is prime.

   Here is sample input and output:

   The number please: 17
   
   17: prime.
   
   
   
   The number please: 60
   
   60: 2 2 3 5
