Exercise set #10

Due: Various

I. search.cpp

The best way to start this project is to copy class.cpp to search.cpp, and simply add some code to the back of search.cpp.

Extend class.cpp by adding code so that, after the class list has been printed, the program asks the user for the name of a student to search for, and then uses a binary search to search for that student in the class. If the student is found in the class, the details of that student should be printed. If the student is not found in the class, an error message should be printed.

Important note: Please do not add features to assigned problems. Asking the user if they want to do this again, for example, will cause problems with my grading program and may result in delay in getting your program back to you (or its return with a request to correct and resubmit).

II. object.cpp

Using the code in search.cpp, create a new program called object.cpp with the following:

• Create an object for student with elements and methods as follows
  • Public
    • Print all of the information about a student
    • Get the student's name
    • Get the student's class average
    • Get the student's grade
    • Constructors
      • Default constructor: initialize everything
      • Other constructor (which you will actually use) with arguments containing the student's name, quiz and exam scores, and which will calculate the student's class average and letter grade
  • Private
    • Student's name, quiz scores, exam scores, class average and grade
• Using the student class, create a ClassRec object with elements and methods as follows
  • Public
    • Class report (same as the printed report in search.cpp)
    • Search (given a student name, find and print (using the print method of the student class) information about the student, and print an error message otherwise).
    • Constructors
      • Default constructor (simply set the class size to zero)
      • Other constructor (which you will actually use): Accept the name of a file (a string) as input, and load the array of student records (see below). In testing, this will be the file "class.dat", but the constructor should accept this as a parameter.
  • Private
    • All implementation variables: class size (an integer), an array (30 max) of student objects.
    • A sort routine to be used by the constructor (sort after all records have been read).
• Finally, write a test driver for your objects (main) which will
  • Construct a class object using the file "class.dat" (the same file used for search.cpp)
  • Print a report of the class using the class report method of the ClassRec class.
  • Ask the user for a name to search for, search the class for that student, printing the information about that student (using the Print method of the student class).
