Donnald Knut that computers are both a science and a technology, and that he spends almost all his life in "art". There are comments that the role and status of the Art of computer programming (the arts of Computer programming) can be compared with Euclid's Theory of Geometry in mathematical history. Its author Donnald Knut (Donald Ervin Knuth) was thus awarded the 1974 Turing Award. Art and Science If you

When it comes to aspect-oriented programming, we can easily relate to object-oriented programming (OOP). The explanation for these two types of programming is that the two programming ideas are just the point of view of programming.OOP focuses on the object, how the object behaves and how it is abstracted. How to encap
