定义一个分数类,通过重载运算符实现分数的四则运算

//Complex.h#pragmaonceclassCComplex{public:CComplex(intreal=0,intimage=0){m_real=real;m_image=image;

#includeusingnamespacestd;classCComplex{floatreal;floatimage;public:CComplexoperator+(CComplex&a)

#includeusingnamespacestd;classComplex{public:Complex(){real=0;imag=0;}Complex(doubler,doublei){real

#include再问：感谢你的回答！只是没有实现++和--的重载，能不能再写点？

classcomplex{public:complex(doubler=0,doublei=0){real=r;image=i;}doublereal;doubleimage;};complexope

#includeusingnamespacestd;classcomplex//复数类声明{public://外部接口complex(doubler=0.0,doublei=0.0){real=

usingSystem;namespacedoing{classdome{staticvoidMain(string[]args){doublea,b,c;Console.Wr

#include#includeclassComplex{public:Complex():_real(0),_imag(0){}explicitComplex(doubler):_real(r),_

#includeusingnamespacestd;classComplex//定义complex类{public:Complex(){real=0;imag=0;}//定义构造函数Complex(d

#includeusingstd::cout;usingstd::endl;//usingnamespacestd;classcomplex{private:doublereal;doubleim

#include<iostream>usingnamespacestd;classComplex{public: Complex(doubler=0,doublei=0):rea

可以

#include#includeclassComplex{public:Complex(floata,floatb):m_real(a),m_imaginary(b){}Complex():m_rea

在头文件mat.h中定义类：/**定义矩阵类*/#include#include#include#include#includeusingnamespacestd;templateclassMatri

#ifndefFRACTION_H_#defineFRACTION_H_#includeintgcd(intm1,intm2);classFraction{public:\x05Fraction(){

#includeusingnamespacestd;classfraction{public:fraction(intn=1,intd=1){num=n;den=d;}fraction&operato

//这是我博客上的分数类例子,重载了+-*/以及#includeusingnamespacestd;classfenshu{intfenzi;intfenmu;public:friendostream

#include#includeclasscomplex{friendstd::istream&operator>>(std::istream&input,complex&c);friendstd::

#includeusingnamespacestd;classComplex{floatReal,Image;public:Complex(floatr=0,floati=0){Real=r;Imag
