Chapter 11: Operator Overloading: Class string

• 11.2 Using the Overloaded Operatos of string
  • empty()
  • += operator
  • substr()
• 11.5 Overloading the Binary Stream Insertion (<<) and Stream Extraction (>>) Operators
  • PhoneNumber.h
    • L.12 ostream must be passed by reference, otherwise you will get a compilation error because it is unable to modify ostream.
    • L.12 PhoneNumber is passed by reference simply because of performance.
    • L.13 PhoneNumber must be passed by reference because you want to read value from istream and store in it.
  • PhoneNumber.cpp
    • L.24 In input, setw() limits the number of characters to be read.
    • L.25 ignore() skips characters
  • Fig11_05.cpp
• 11.7 Overloading the Unary Prefix and Postfix ++ and -- Operators
  • Date.h
  • Date.cpp
    • L.41 The prefix increment operator (++n) returns a reference to the object
    • L.49 The postfix increment operator (n++) returns a copy of the object
  • fig11_08.cpp
• 11.9 Dynamic Memory Management
  • fig11_09.cpp
    • L.69 operator[] can also be overloaded.
  • Array.h
    • L.15 The argument to a copy constructor should be a const reference to allow a const object to be copied.
  • Array.cpp
    • L.51 avoid self-assignment
• 11.13 Implicit Conversion with Single-Argument Constructors
  • Array.h
    • Same as the above
  • Array.cpp
    • Same as the above
  • Fig11_12.cpp
    • L.13 Implicitly convert 3 to an Array
• explicit Constructors
  • Array.h
    • L.14 explicit
  • Array.cpp
    • Same as the above
  • Fig11_13.cpp
    • L.13 generate a compilation error.
    • L.14 explicitly call a constructor
• Ex 11.8 Complex Class
  • Complex.h
  • Complex.cpp
  • fig11_16.cpp
• Ex 11.9 HugeInt Class
  • Hugeint.h
  • Hugeint.cpp
    • Observe how the result of addition is returned.
