面向对象程序设计(Object-oriented programming,OOP)是种具有对象概念的程序编程典范,同时也是一种程序开发的抽象方针。面向对象三大特征 —— 封装、继承、多态封装把客观事物封装成抽象的类,并且类可以把自己的数据和方法只让可信的类或者对象操作,对不可信的进行信息隐藏。关键字:public, protected, private。不写默认...
Not escaping out quotation marks.This is the easiest way to throw the compiler into an error because it won’t know what was passed along to the function or not. Using printf() too casually for debugging.While it’s a common practice, it can be detrimental; it can spit out a significan...
Security vulnerabilities of the top ten programming languages LV13090 Objective-C does address potential access-control problems through the use of objects that encapsulate data. Based on this approach, the optimal method is to show only a public interface that hides the internal operations. Therefore...

We will discuss more the way we analyze our surroundings in Chapter 6, OOP and Encapsulation. But as an answer to our starting question, we need new types because we use them to analyze our problems at a higher level of logic, close enough to our human logic. Here, you need to become...
