设计一个小型的复数类（C++标准库complex提供复数类），这里为了说明重载运算功能而设计，在小型复数类MiniComplex中，数据成员：实部与虚部。函数远远主要是重载进行复数运算的各种操作符。由于各种运算符功能的限制，将输入与输出运算符重载为友元函数，使得复数的输入与输出更加方便快捷，成员函数重载+，—，*，和/运算符来进行复数的加法、减法、乘法、和除法运算，重载逻辑运算符= =进行复数的相等比较。-Design of a small category of plural (C++ Standard library complex to provide the plural category), here to illustrate the design features heavy-duty computing, in a small complex MiniComplex category, the data members: the real part and imaginary part. Function is far from heavy-duty computing to a variety of complex operator. Operator function of a variety of constraints, will be input and output overloaded operator functions for the Friends of yuan, making the plural of the input and output faster and more convenient, a member of Function Overloading 2B !,-,*, and/operator to carry out the plural of the adder , subtraction, multiplication, and division operations, overloaded logical operator = = for the plural of the same comparison.
