Object oriented programming vs Object -Based Programming

Object oriented programming vs Object -Based Programming

1. It must be remembered that any system developed in OOP methodology , must meet at least the following characteristics:

   • • The system has been designed , clearly identifying the relevant class and hierarchy. • Using polymorphism • Clear definition in each class of its methods • Encapsulation of information • Modularization • Exceptions and Concurrency • Partnership Objects

2. USING OBJECT-ORIENTED PROGRAMMING LANGUAGE C

   • Although we had already indicated that the C language is not strictly oriented OOP language , you can follow certain rules , to be used strictly under this methodology .
     • Class Definitions
       • The concept of class does not exist as such in C. For this you can use the data type structure ( struct) mechanism to define and encapsulate all the information relating to it , ie , data members and methods.
     • heritage
       • Inheritance in C , is implemented by referencing the upper structure in the structure derived . Importantly, when inheritance is multiple references to the upper classes are solved in the same way .
     • Resolution Methods
       • The methods inherent in a class are implemented by declaring them within the structure (class ) to which they belong , allowing them to be resolved at compile time
     • associations
       • Implementing association relationships between classes or objects thereof, are performed , except JAVA , in the same way as in most OOP languages ​​oriented : using pointers
     • Object Creation and Destruction
       • The creation and destruction of objects is resolved at compile time , explicitly using the malloc () and free () respectively
     • templates
       • Reducing code duplication mechanism that is already inherent in languages ​​of POO area through the use for example of templates ( template ) in C ++ or generics (generic) ADA in C can be implemented using macros , with to not use types, which is the only obstacle in the area not own OOP languages
