Write a program that allows the user to convert a temperature given in
degrees from either Celsius to Fahrenheit or Fahrenheit to Celsius. Use the following formulas: Degrees_C = 5 (Degrees_F ? 32) / 9 Degrees_F = (9 (Degrees_C) / 5) + 32 Prompt the user to enter a temperature and either a C or c for Celsius or an F or f for Fahrenheit. Convert the temperature to Fahrenheit if Celsius is entered, or to Celsius if Fahrenheit is entered. Display the result in a readable format. If anything other than C, c, F, or f is entered, print an error message and stop. This project uses selection to enhance the program FtoC developed in Chapter 2. The solution includes a default case if an incorrect character (anything other than a ‘C’ or ‘F’, either upper or lower case) is entered for the units. A common error is to write the while control expression as an OR instead of an AND, so the loop does not end when either ‘Q’ or ‘q’ is entered. With an OR expression one or both sides of the expression will always be true (if ‘Q’ is entered, the variable quit is not equal to ‘q’, and vice versa); quit must be both not equal to ‘Q’ and not equal to ‘q’ to enter the loop.
Consider a STUDENT relation in a UNIVERSITY database with the following attributes (Name, SSN, Local_phone, Address, Cell_phone, Age, GPA). Note that the cell phone may be from a different city and state (or province) from the local phone. A possible tuple of the relation is shown below:
a. Identify the critical missing information from the LocalPhone and CellPhone attributes as shown in the example above. (Hint: How do call someone who lives in a different state or province?)
b. Would you store this additional information in the LocalPhone and CellPhone attributes or add new attributes to the schema for STUDENT?
c. Consider the Name attribute. What are the advantages and disadvantages of splitting this field from one attribute into three attributes (first name, middle name, and last name)?
d. What general guideline would you recommend for deciding when to store information in a single attribute and when to split the information?
