Slides As Shown:

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

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

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

• 2-D Arrays : [slide view] [print view]

Topics Covered:

• Revisited two issiues in Project 1 (see Announcements slides above):
  1. How to handle end of file issues.
  2. What if we wanted to implement "Lazy Evaluation" for medianRating? We'd have to use the mutable keyword.
• Continued discussion of operator overloading (see slides), including:
  1. "Outward" type conversion.
  2. overloading input and output operators.
• Discussed new, delete and destructors for dynamic memory allocation.
• Looked at various ways to define 2-dimensional arrays.
