偶有一程序不知道问题在哪 请诸位帮我检查检查 #include<iostream.h> class complex { double mX,mY; public: complex(double vx=0,double vy=0) {mX=vx;mY=vy;} friend ostream& operator<<(ostream&,complex&); friend istream& operator>>(istream&,complex&); }; ostream& operator <<(ostream& output,complex& c) { output<<"c.mX"<<"+"<<c.mY<<"i"<<endl; return output;

}

istream& operator >>(istream& iutput,complex& c) { cout<<"input mX and mY:"; input>>c.mX>>c.mY; return input;

} void main() { complex c1(1,2 ; cout<<c2; }

是这样吗？ #include<iostream.h>

class complex { double mX,mY; public: complex(double vx=0,double vy=0) {mX=vx;mY=vy;} friend ostream& operator<<(ostream&,complex&); friend istream& operator>>(istream&,complex&); };

ostream& operator <<(ostream& output,complex& c) { output<<"c.mX"<<"+"<<c.mY<<"i"<<endl; return output;

}

istream& operator >>(istream& input,complex& c) { cout<<"input mX and mY:"; input>>c.mX>>c.mY; return input;

}

void main() { complex c1(1,2 ); cout<<c1; }

#include<iostream.h>

class complex { double mX,mY; public: complex(double vx=0,double vy=0) {mX=vx;mY=vy;} friend ostream& operator<<(ostream&,complex&); friend istream& operator>>(istream&,complex&); };

ostream& operator <<(ostream& output,complex& c) { output<<"c.mX"<<"+"<<c.mY<<"i"<<endl; return output;

}

istream& operator >>(istream& input,complex& c) { cout<<"input mX and mY:"; input>>c.mX>>c.mY; return input;

}

void main() { complex c1(1,2 ); cout<<c1; }

呵呵！我的错误太不应该啦。谢谢二位的检查 不过 经过我的调试 output<<"c.mX"<<"+"<<c.mY<<"i"<<endl; 改成output<<c.mX<<"+"<<c.mY<<"i"<<endl; 就完全正确啦 总之谢谢啦
