网络封包技术,书本实例实用性高.学网络编程的看看不错的-packet network technology, high textbook example of practicality. Network Programming look at the good

最小二乘法求超定线性方程组得C＋＋模板，还包括矩阵求逆，矩阵乘法等小函数(Overdetermined least-squares method of linear equations have to C templates, also includes matrix inversion, matrix multiplication, such as small function)

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.)
