Question

求大神 编写c++复数计算器源代码

要求 1设计复数计算器可以重复进行+ - * 除和两个复数比较运算
2用cout和cin输出和输入复数
3设计复数类 complex
设计重载复数 + - * 除 《 》
设计复数相加减乘除 比较的函数

Answer 1

#include<iostream>
using namespace std;
class Complex{
double real;
double imag;
public:
Complex(double r=0,double i=0)
{
real=r;
imag=i;
}
Complex operator+(const Complex& a)
{
Complex b;
b.real=real+a.real;
b.imag=imag+a.imag;
return b;
}
Complex operator-(const Complex& a)
{
Complex b;
b.real=real-a.real;
b.imag=imag-a.imag;
return b;
}
Complex operator*(const Complex& a)
{
Complex b;
b.real=real*a.real-imag*a.imag;
b.imag=real*a.imag+imag*a.real;
return b;
}
Complex operator/(const Complex& a)
{
Complex b,c;
c.real=a.real;
c.imag=-a.imag;
b.real=c.real*a.real-c.imag*a.imag;
b.imag=c.real*b.imag+c.imag*a.real;
return b;
}
friend ostream& operator<<(ostream& os,const Complex& a)
{
if(a.imag >0)
os<<a.real<<"+"<<a.imag<<"i"<<endl;
else
os<<a.real<<a.imag<<"i"<<endl;
return os;
}
friend istream& operator>>(istream&is,Complex& a)
{
is>>a.real;
is>>a.imag;
return is;
}

};

void main()
{
Complex a,b;
Complex c;
cin>>a>>b;
cout<<a<<endl<<b<<endl;
c=a*b;
cout<<c<<endl;
}
复数不能比较大小！
希望回答能帮到你，哪里不清楚再问。
