谁来帮我找一下bug

[NeoHeart]

我的代码是如下，他总是说我unexpect end of file，谁来帮我编译一下，看看问题出在哪 谢谢了


#include <iostream.h>
#include <math.h>

class equation
{
public:
void twoRealAnswer(int a,int b,int c);
void oneRealAnswer(int a,int b,int c);
void twoUnrealAnswer(int a,int b,int c);
private:
float a,b,c;
float realsection,unrealsection;
}


class equation::twoRealAnswer(int a,int b,int c)
{
realsection=-b/2*a;
unrealsection=sqrt((b*b-4*a*c)/2*a);
}

class equation::oneRealAnswer(int a,int b,int c)
{
realsection=-b/2*a;
unrealsection=0;
}

class equation::twoUnrealAnswer(int a,int b,int c)
{
realsection=-b/2*a;
unrealsection=sqrt((4*a*c-b*b)/2*a);
}


void main()
{
equation A;
cout<<"input the argument of a,b,c:";
cin>>A.a>>A.b>>A.c;
if ((A.b*A.b-4*A.c*A.a)>0)
{
A.twoRealAnswer(int a,int b,int c);
cout<<"answer1="<<A.realsection+A.unrealsection<<endl;
cout<<"answer2="<<A.realsection-A.unrealsection<<endl;
}
else if((A.b*A.b-4*A.c*A.a)==0)
{
A.oneRealAnswer(int a,int b,int c);
cout<<"answer="<<A.realsection+A.unrealsection<<endl;
}
else if((A.b*A.b-4*A.c*A.a)<0)
{
A.twoUnrealAnswer(int a,int b,int c);
cout<<"answer1="<<A.realsection<<"+"<<A.unrealsection<<"i"<<endl;
cout<<"answer2="<<A.realsection<<"+"<<A.unrealsection<<"i"<<endl;
}
}

class定义后面需要分号

而类的成员函数在定义时class关键字不是必需的

[cat_dog]

class equation
{
public:
void twoRealAnswer(int a,int b,int c);
void oneRealAnswer(int a,int b,int c);
void twoUnrealAnswer(int a,int b,int c);
private:
float a,b,c;
float realsection,unrealsection;
} //这里要加分号

有每个类结束处加分号。

equation A;
cout<<"input the argument of a,b,c:";
cin>>A.a>>A.b>>A.c;//你输得进来吗？a,b,c是保护成员？

[一叶还真不知秋]

cout<<"answer1="<<A.realsection<<"+"<<A.unrealsection<<"i"<<endl;
cout<<"answer2="<<A.realsection<<"+"<<A.unrealsection<<"i"<<endl;
//你输得出吗，都用保护成员，保护成员在这种情况下不可见!

to xteaj(半桶水
的确错了，应该用个成员函数去修改a,b,c 吧？
