设计复数类Complex成员数据包括实部real和虚部imag类型都是double。根据给定的main函数设计必要的成员函数。注意虚部为负数和不存在的情况main函数已给定提交时只需要提交main函数外的代码部分#includeiostreamusing namespace std;你提交的代码在这里int main Complex c1; coutShow object c1;

#include using namespace std;

class Complex{ private: double real, imag; public: Complex():real(0),imag(0){}//无参构造函数 Complex(double r, double i):real(r),imag(i){}//有参构造函数 void Set(double r, double i){//设置实部和虚部 real = r; imag = i; } void Show(){//输出实部和虚部 if(imag == 0){ cout<<real<<endl; } else if(imag > 0){ cout<<real<<"+"<<imag<<"i"<<endl; } else{ cout<<real<<imag<<"i"<<endl; } } };

int main() { Complex c1; cout<<"Show object c1:"; c1.Show(); double real,imag; cin>>real>>imag; Complex c2(real,imag); cout<<"Show object c2:"; c2.Show(); cin>>real>>imag; cout<<"Reset and Show object c1:"; c1.Set(real,imag); c1.Show(); return 0;
