New Features in ANSI C++ Standard

How to Use New Features in ANSI C++ Standard.

1)      Newly added  data types in ANSI C++:

a)bool  data type

b)wchar_t data types

c) wide_character Literals

a)bool  data type:

bool  bb; //declarion of bool data type

bb=true;  //assignment of true value

bool  bb2 = false; //declaration and initialization(to true) simultaneously

b)wchar_t data types:

                                e.g.    L  ‘ms’ //example of wide character Literal.

         2)      New Operators:

A)     Static_cast operator

B)      Const_castoperator

C)      Reinterpret_cast operator

D)     Dynamic_cast operator

E)      Typeid operator

       3)      Namespace

       4)      Some old style header files are renamed.for example:
