disklib
Due to an increase in demand for and questions about direct disk
access for Micrososft platforms, and due to the fact that Microsoft
has no API for direct disk access, I am releasing this library
much earlier than I intended at that start. I am still working on
this code.

4) 创建一个名为Complex的类,进行复数的算术运算。复数的形式为:
realpart+imaginarypart*i
用浮点变量表示类的private数据。提供构造函数,能够对所声明的该类对象进行初始化。在不提供初始化值的情况下,该构造函数应包含默认值。针对以下功能,分别提供一个public成员函数。
(1)两个复数相加;
(2)两个复数相减
(3)用(a, b)的形式打印复数,其中a为实部,b为虚部。
(4) Create a class called Complex, and perform complex arithmetic operations. Plural form: realpart+imaginarypart* i said private data class with floating point variables. Provide a constructor, the object can be declared for the class is initialized. In the case do not provide initialization values, the constructor should contain default values. For the following functions, which provide a public member function. (A) two complex numbers (2) the subtraction of two complex (3) (a, b) in the form of plural printing, where a is the real part, b is the imaginary part.)
