  4. Object Oriented Concepts


  5. Part -08


  6. Pure Virtual Functions A pure virtual function is a virtual function that has no definition within the base class. . If a class contains at least one pure virtual function, that class is called as abstract class. The derived class should implement the pure virtual function. If not, derived class also will be an abstract class. Abstract class cannot be instantiated. i.e, obiect of abstract class cannot be created


  7. . The only purpose of abstract class is Generalization. i.e. It declares the prototype of collection of similar classes in the hierarchy of classes (Standard interface) Pointer to an abstract class can be declared.


  8. Namespace A namespace is a named area of scope in which all identifiers created by the programmer are guaranteed to be unique The identifiers in a namespace may represent variable names, constant names, function names, structure names, class names or other namespaces. A namespace can be defined either at the global level or within another namespace (nested namespaces)


  9. The std Namespace . The standard C++ library defines it's entire library in it's own namespace called std. . The std namespace has to be included in the beginning of a program as using namespace std; This causes the std namespace to be brought into the current namespace. . The namespace std contains all the function and the classes defined in any of these libraries If you don't declare using namespace std; at the beginning of the program, then you must use standard objects as given below


  10. Exception Handling An Exceptional condition is an event that occurs during the execution of C++ program (runtime anomalies) causing a program to interrupt. Examples: Out-of-bound array subscript, arithmetic overflow or underflow, division by zero, out of memory, invalid function parameter, etc., . An exceptional condition may be either an unexpected error or an excepted error at an unpredictable time
