Today I saw the object-oriented analysis method , This paper compares the difference between object-oriented and process oriented programming , See an example that is easy to understand , Take Gobang for example .

Process oriented programming ： The idea of programming is based on the actual process of playing chess , Start the game –> Go ahead with sunspots –> Drawing picture –> Judgement of winning or losing –> Turn white –> Drawing picture –> Judgement of winning or losing –> Go back to step two –> Output results . The process of writing a program is to realize each step layer by layer . The advantage is that performance is higher than object-oriented programming .（ Because class calls need to be instantiated ,new You need to allocate memory for the object , Compare the consumption of resources ？？）
object-oriented programming ： It can be said that it is divided into user layer at the functional level 、 Checkerboard layer 、 Rule layer . The user layer is the black and white sides of the executive , Responsible for receiving user input , Then it goes to the chessboard layer ; The chessboard layer is responsible for drawing pictures , Then pass the chess situation to the rule layer ; The rule layer is used to judge whether the chess game continues 、 Whether any side has won , And end the game . Object oriented programming has encapsulation 、 polymorphism 、（ inheritance , Forget about this ..）. The advantage is relative to process oriented programming , Easy to maintain 、 Easy to expand .
