Assigned Reading:  1.3, 4.1

Slides As Shown:

• Announcements, etc: [slide view] [print view]

• C++ Strings : [slide view] [print view]

• C++ Primer : [slide view] [print view]

Topics Covered:

• Announcements.

• Recapped vectors: Vector Methods , More Vector Methods .
  • Discussed size() versus capacity().
  • The [] operator for vector doesn't check bounds, but the at() method does: overrun2.cpp, overrun3.cpp.
  • We can modify the vector class and "derive" a new PascalIntArray class that does a range check. We also change the [] operator to start indexing at 1 instead of 0. Just for fun we add a bubblesort() member function: PascalIntArray header, PascalIntArray implementation, piatest.cpp, and piatest.cpp output.

• Introduced C++ string class. See slides above.

• Considered some features of C++ that C programmers really need to be aware of, including: console I/O, type casting and constants.

• Some simple I/O programs with problems: iotest1.cpp, iotest2.cpp and iotest3.cpp.
