Working with Selection Statements

Code due to the Program Submission System on by 9/18 at 11:59pm

Introduction

This week we have been working with selection statements.  Let's see if you understand this idea.

Notes and requirements:

• Make sure that you save your programs in the correctly named files
• Make sure that you are following the proper policies regarding code based homework
• Use meaningful variable names
• Your programs should ask for input in the exact order specified in the customer requests below.

Program 2.1 (5 points)

Create a program named tip.py

• I always tip 20% of the meal cost. But I know that people working at inexpensive places work as hard to serve me as those in expensive places so I always tip at least $2.50. Produce code that will calculate my tip.
• Accept an input value as a float for the meal cost, and calculate and print the tip.
• Here is an example:
  
• Here is another example:
  

Program 2.2 (8 points)

• Produce code to accept a number indicating the percentage of the sky that has clouds and report a cloudiness descriptor, according to the following chart.



Percentage	Description
30 or less	Clear
between 31 and 70	Partly cloudy
between 71 and 99	Cloudy
exactly 100	Overcast

Program 2.3 (12 points)

• Normal height for US females is 64 inches plus/minus 2.5 inches and for US males it is 69.5 inches plus/minus 3 inches. Accept input values indicating gender (F or M) and height and then report whether a person with those characteristics is within the average height range.
• Hint: Is 66.5 inches in the average range or not for a female person? (It is in this case, but 66.6 is not.) Be sure you test all of these "boundary cases".
• Here is an example:

Final Submission

Please submit all three programs to the Program Submission System by the due date and time.
