The object-oriented approach is known to introduce a significant performance penalty in terms of memory and time compared to classical procedural programming. In this paper, we have analyzed the execution speed of the different programs generated by the compilers of C and Java. The investigation ...

The design process for each method of programming differs in many ways. With Object-oriented Programming, designs can be reused and recycled throughout the program where Procedural Programming is usually not able to do this. Additionally planning out the process of the design is much different wit...
(1)procedural model,即C语言的模式 (2)ADT model,即所谓的封装,将属性与方法封装在一起 (3)object-oriented model,支持继承、多态(只有通过指针或引用来使用,往往只有到执行期才知道指向哪种object)。 5.class object所占内存计算: nonstatic data member总和+aligment填补(32位机器为4)+支持虚拟机制产生的额外...

Object-oriented vs. functional programming methods In essence, functional programs behave like common math functions, such as the calculations behind a conversion from Celsius to Fahrenheit. With functions, the same inputs consistently lead to the same result. A "pure" function is deterministic and ...
Most modern programming languages are considered object-oriented languages, but some are more object-oriented than others, depending on how the OOP principles are implemented in the language and how they are used. Some languages that were originally designed as procedural programming languages have, ov...
functionality and wrap it inside something called an object. This is called theobject orientedprogramming paradigm. Most of the time you can use procedural programming, but when writing large programs or have a problem that is better suited to this method, you can use object oriented programming ...
In programming, properties are represented by objects, and behaviors are represented by functions. And thus, procedural programming represents reality fairly poorly, as it separates properties (objects) and behaviors (functions). What is object-oriented programming?
Object-oriented programming(OOP) is aprogramming paradigmbased on the concept of "objects", which may containdata, in the form offields, often known asattributes;and code, in the form of procedures, often known asmethods.A feature of objects is that an object's procedures can access and oft...
