1. Quiz 1: write a menu-driven user-interface (as a main program) for testing a function (a test driver). Options:
   • 0 = enter data
   • 1 = print data
   • 2 = call function
   • 4 = exit
2. Recap: struct in C/C++.
   • Example: struct CustRec
     {
     int id;
     float balance;
     };
     
   • Declare variables of this type:
     CustRec c1, c2;
     
   • Initialize
   • Access components.
   • Arrays of records.
   • Passed as parameters. IN: value is copied. Example: sorting an array of CustRec by id or by balance.
3. In-class lab (nothing to submit): Example of a sorting program using struct and templates in C++. Use the code of the program for selection sort from last time. Modify it:
   • To make it as readable as possible (add spaces, dividers, your name, account, etc.), comments.
   • Add to it the feature to sort not only an array of characters and an array of integers, but also an array of CustRec, by id or by balance. Use templates.
   • Extra credit: add a menu-driven interface in the test driver (main function) to allow the user to choose what to do (i.e. what kind of data to sort).
4. Preview of homework 4. Use this as a model. It is a program to test a Seelction Sort function, done with templates and passing functions as paramaters. ANother solution is to use the idea discussed in class, of using a variable to tell the program how to compare the data, in each case (and there will be lots of if's in some functions).
