Up]

Assigned Reading:  10.1-10.3

Slides As Shown:

• Overloading Operators : [slide view] [print view]

• Dynamic Memory Allocation: [slide view] [print view]

Topics Covered:

• Project 2 questions.

• Finish overloading operators.

• Using new and delete for memory allocation.

• Memory allocation and destructors:

  Examples:

  • A class DMC with a dynamically allocated array: dmc.h, dmc.cpp.
  • A simple example with destructors being invoked when objects go out of scope: main1.cpp.
  • Destructors and loops: main2.cpp.
  • Temporary objects in expressions: main3.cpp.
  • DMC as data member in AClass: main4.cpp.
