*问题描述:请用类的成员函数,定义复数类重载运算符+、-、*、/,使之能用于复数的加减乘除
*输入描述:
*程序输出:
#include <iostream> using namespace std; class Complex { public: Complex(){real=0;imag=0;} Complex(double r,double i){real=r; imag=i;} Complex operator+(const Complex &c2); Complex operator-(const Complex &c2); Complex operator*(const Complex &c2); Complex operator/(const Complex &c2); void display(); private: double real; double imag; }; //下面定义成员函数 Complex Complex::operator+(const Complex &c2) { Complex c; c.real=real+c2.real; c.imag=imag+c2.imag; return c; } Complex Complex::operator-(const Complex &c2) { Complex c; c.real=real-c2.real; c.imag=imag-c2.imag; return c; } Complex Complex::operator*(const Complex &c2) { Complex c; c.real=real*c2.real-imag*c2.imag; c.imag=imag*c2.real+real*c2.imag; return c; } Complex Complex::operator/(const Complex &c2) { Complex c; c.real=(real*c2.real+imag*c2.imag)/(c2.real*c2.real+c2.imag*c2.imag); c.imag=(imag*c2.real-real*c2.imag)/(c2.real*c2.real+c2.imag*c2.imag); return c; } void Complex::display() { cout<<real<<'+'<<imag<<'i'<<endl; } //下面定义用于测试的main()函数 int main() { Complex c1(3,4),c2(5,-10),c3; cout<<"c1="; c1.display(); cout<<"c2="; c2.display(); c3=c1+c2; cout<<"c1+c2="; c3.display(); c3=c1-c2; cout<<"c1-c2="; c3.display(); c3=c1*c2; cout<<"c1*c2="; c3.display(); c3=c1/c2; cout<<"c1/c2="; c3.display(); return 0; }
(ˇ?ˇ) 想在成员函数中直接用return,结果写了好几次都写不出来,5555555555~~~~最后屈服了
