CPS 100E, Fall 1996 Inlab 5

Name:

Lab Section:

You should answer the following questions and either turn in the sheet during lab, or answer the questions when you submit your README file. These questions are worth 2 out of the 10 points for each lab. You don't need to get all the answers right to get the 2 points, but you must try.

It's ok to ask a UTA or TA for help, but first you must try to find the answers on your own.

  1. Why do you think that an ID Number is needed for each CD?



  2. What other information might be useful to have for each CD? What structs or class would change to add the information?



  3. Why was getline used rather than >> in reading the database (think about group and title names.)



  4. A version of getline with three parameters is used in the DoRead function from usedb.cc: getline(input,price,':') What purpose does the third parameter have.



  5. How many times was the vector myList in the CDlist resized when reading in data/cd.dat assuming that was the first file that was read into the program? (Hint: what is the value of INITIAL_SIZE and how many CDs are stored.)
