• Chapter 10: STL

Learning Note

1. Chapter 5

• Only use friend when declare a function, but not when define a function.
• No type is needed when declare and define constructors.
• Memeber function names in class cannot be the same with member data name.
• Declare type ostream& when overloading <<.
• << is a binary operator with first arguement of type ostream& and second arguement string.

2. Chapter 6

• -> is used for pointer to call class memebers, equivalent to (*pointer).member

3. Chapter 7

• virtual specifier specifies virtual function. The derived class is optional to override this memeber function.
• virtual void func()=0 define a pure virtual function or pure virtual method which is required to be implemented by a derived class if the derived class is not abstract.
• When declare function with function pointers as argument, it must contain the types the function's arguments. For example, (*func)(double, int).

5. Chapter 9

• Remember to define read-only functions as const, especially in base class.
• Remember to declare and define destructor in header file.
• size methid in vector class return unsigned int object. Define counter correspondingly when use it in the loop.
• Reference is a name constant for an address, acts mostly like a pointer. However, oo explicit dereferencing operator * should be used when return the values. Furthermore, to assign an address of a variable to a reference variable, no address-of operator & is needed.

6. Chapter 10

• When call a template function, one can explicitly specify the type. C++ support implicit template parameter deduction, so one can ignore the type as well.
