"Learning Notes" C # Object oriented

Object oriented

• Process-oriented-analyze the steps required to solve the problem and then step through it
• Object-oriented-decomposing the things that make up a problem into objects
• An object is used to describe the behavior of something in a problem-solving process.
• Object-oriented three major features: encapsulation, inheritance, polymorphism
• Object-oriented program is more reusable, flexible and extensible
