wangxijun
附注
置于“～”是析构函数；析构函数因使用"~"符号(逻辑非运算符)，表示它为腻构造函数，加上类名称来定义。
；析构函数也是特殊的类成员函数，它没有返回类型，没有参数，不能随意调用，也没有重载，只有在类对象的生命期结束的时候，由系统自动调用。
有适放内存空间的做用!
虚函数是C++多态的一种表现
例如：子类继承了父类的一个函数（方法），而我们把父类的指针指向子类，则必须把父类的该函数（方法）设为virturl（虚函数)。
使用虚函数，我们可以灵活的进行动态绑定，当然是以一定的开销为代价。
如果父类的函数（方法）根本没有必要或者无法实现，完全要依赖子类去实现的话，可以把此函数（方法）设为virturl 函数名=0
我们把这样的函数（方法）称为纯虚函数。
如果一个类包含了纯虚函数，称此类为抽象类
wangxijun
附注
主要的区别是变量的作用范围不同。全局变量在全局范围内都有效，而局部变量只在声明此变量的作用域内有效。
全局变量是属于实例的,在初始化对象的时候初始化，生命周期与该实例相同，之所以叫全局变量是因为该实例中的所有方法或属性都可以引用；局部变量是在实例方法内或static块中，生命周期从调用该方法到该方法退出，并且只有该方法能够引用之。
全局变量和局部变量的区别是在存储器中位置不同，具体说，全局变量存储在数据段中，局部变量都有可能，一般来说在堆栈段

atoi是把字符串转化为整形数，比如“980”变成980

附注
除关键字不同外(class,struct)的唯一区别是,
结构在默认情况下的成员是公共(public)的,
而类在默认情况下的成员是私有(private)的。
在C++中,结构是特殊的类。
class是从struct发展而来的。之所以将struct和class都保留，是因为：
1、提出class是为了强调一种概念。
2、保留struct是为了照顾到大多数人的习惯。
struct和class是有区别的。
struct保证成员按照声明顺序在内存中存储。class不保证等等
而它们都可以继承，实现多态等。但也有少许区别。比如：
struct A { }；
class B : A{ }; //private继承
struct C : B{ }； //public继承
这是由于class默认是private，struct默认是public。
一般说来，struct和class可以换用（当然要注意一些语法问题）。
而struct更适合看成是一个数据结构的实现体，
class更适合看成是一个对象的实现体，
对私有成员进行保护，还提供与外界的接口。
从习惯上更喜欢用class。

wangxijun
附注
宏的缺点是不进行类型检查，有点是可以左某些特殊的工作，比如字符串连接的，宏在预处理阶段展开。 C++的语言设计者本人强烈建议使用inline函数来代替宏。
含参数的宏缺点主要是可读性差，容易出错，优点是在预处理阶段完成，不占用编译时间

不是！ 在 main 前面定义一个类数据类型， 比如 ClassT example;他有自己的构造函数，这个构造函数在main之前应该就开始执行了。
main 不过是一个程序的入口而已。 至于所有的动作呢， 那就多了， 用户也有动作嘛！

KPMG 笔试题
“The big economic difference between nuclear and fossil-fuelled power stations is that
nuclear reactors are more expensive to build and decommission, but cheaper to sun. So disputes
over the relative efficiency of the two systems revolve not just around prices of coal and uranium
today and tomorrow, but also around the way in which future income should be compared with
current income.”

“At any given moment we are being bombarded by physical and psychological stimuli
competing for our attention. Although our eyes are capable of handling more than 5 million bits of
