Chapter 14: Tempaltes

1. 14.2 Function-template specializations of function template printArray
   • L.7~8 Function Template
   • Calling functions in L.29, L.34, L.39 causes the compiler to instantiate printArray function-template specializations with type int, double, character, respectively.
2. 14.4 Class Templates
   • Stack class template
     • L.6~7 The class definition is preceded by the header template<typename T>.
     • L.40~41 Member-function definitions of a class template are function templates.
     • L.41 Scope resolution operator is used with the class-template name Stack<T> to tie each member-function definition to the class tempalte's scope.
   • fig14_03.cpp
     • L.9 Stack<double> doubleStack(5); // size 5
     • L.30 Stack<int> intStack; // default size 10
3. Creating Function Templates to Test Class Template Stack<T>
   • Stack class template
     • Same as the above.
   • fig14_04.cpp
     • In the previous example, the code to manipulate doubleStack and intStack are almost identical, so this is a great opportunity to use a function template.
     • L.11 The function template takes four arguments:
       1. a reference to an object of type Stack<T>
       2. a value of type T that will be the first value pushed onto the Stack<T>
       3. a value of type T to increment the value
       4. a string representing the name of the Stack<T> object
