- Recap: struct in C/C++.
- Declare variables of this type:
CustRec c1, c2;
- Declare an array of records of this type:
- Initialize: s1.id = 1;
- Access components. Dot notation.
- Arrays of records. To access, use both  for accessing the
array elements, and dot, for the components (field) of the
- Records within records (the "party" structure, with an array
of "student" records inside).
- When passed as parameters. IN: value is copied. OUT
(reference): only a pointer (reference) to the record is passed.
- Example: swapping two records. See
swap.cpp, where we have two different
functions for two different types of records.
- Templates in C++.
Motivation: sorting other data types, not just
integers. Instead of writing several separate functions, write only
one "template function" and use it for several types of data.
Example of finding the maximum, swaping and sorting other types
of data without rewriting the whole
program. Using templates in C++.
- In-class program reading exercise: the modified swap-testing program
with templates, swapT.cpp. It swaps two elements of
CustRec or Student type.
- In-class exercise, done with Ileana in preparation for Hw 3 (not
finished - doesn't have read/print functions):
- Starting to make the sort function into a templated one:
The rest is part of your next Hw 3.
- Preparation for next Homework: Insertion Sort. You will have to implement it
both on integers and as a template (tested on integers and characters).
