EC notes, Part I: 1. C + + as a language federation

C + + can be thought of as a combination of the following four sub-languages
1.C language
Efficient, built-in data types, arrays, chunks, statements, pointers, preprocessor, no overloads, exceptions, templates
2. Class
Construction, destruction, encapsulation, inheritance, polymorphism, late binding
3. Templates
Template meta-programming, not concerned with data types, only concerned with the structure and algorithm
4.STL
Standard template libraries, containers, iterators, algorithms, function objects
