这题太可怕了.... 一堆错误，完全不知道如何下手啊 TAT

Question

 

#include <iostream>

using namespace std;

class CComplex

{

public:

CComplex()

{

real = 0.0; 

imag = 0.0;

}

CComplex(float x, float y)

{

real = x;

imag = y;

}

CComplex operator + (CComplex &obj1, CComplex &obj2)

{

CComplex obj3(obj1.real + obj2.real, obj1.imag + obj2.imag);

return obj3;

}

CComplex &operator++(CComplex &obj)

{

obj.real += 1;

obj.imag +=1;

return obj;

}

void print()

{

cout<<real<<"+"<<imag<<"i"<<endl;

}

private:

float real;

float imag;

};

CComplex &operator--(CComplex &x)

{

x.real -= 1;

x.imag -= 1;

return x;

}

void main()

{

CComplex obj1(2.1,3.2);

CComplex obj2(3.6,2.5);

cout<<"obj1=";

obj1.print();

cout<<"obj2=";

obj2.print();

CComplex obj3 = obj1 + obj2;

cout<<"befor++, obj3=";

obj3.print();

++obj3;

cout<<"after++, obj3=";

obj3.print();

--obj3;

cout<<"after--, obj3=";

obj3.print();

CComplex obj4 = ++obj3;

cout<<"obj4=";

obj4.print();

}

全是错误  看得头晕了不懂怎么改。。。。
