面向对象程序设计（APS 口述稿·中英）
核心内容
面向对象程序设计 object-oriented programming
First, an object is something that has three properties: state, behavior, and identity. A class is a collection of objects that share the same structure and behavior. Inheritance describes relationships between classes. The feature of this program is encapsulation (storing all objects, attributes, and data in one entity), inheritance (when one object copies a feature of another object), and polymorphism (the different actions of different objects receiving the same information at the same time). The advantage is more convenient to expand the existing code, reduce the conversion process, convenient to control the software complexity. The disadvantage is that the operation efficiency is low and the content of class is too large
It's in C++. Common language types in C++ are integer constants, floating point, char, and arithmetic operators. There are break statement (exit the loop), continue statement (continue the loop), while statement (continue the loop if the condition is met, exit if it is not met), and for statement (loop within a certain range, exit beyond the range).
