大家看一下错误何在

void setvalues(double zr,double zi);
void setRealPart(double zr);
void setImagePart(double zi);

下面是complex.cpp文件
#include<iostream.h>
#include<string.h>
#include"complex.h"
int complex::mNo=0;
void complex::setvalues(double zr,double zi)

}

{

}

}


complex::complex()
{
realPart=0;
imagePart=0;
mNo++;
mName=new char[8];
strcpy(mName,"complex");

cout<<mName<<mNo<<endl;
}

complex::~complex()
{
delete mName;
}


下面是main_complex.cpp文件


#include<iostream.h>
#include"complex.h"
void main()
{
double zr,zi;
char ch='y',add_or_sub; //判断程序是否结束
complex zc1,zc2,zc3;
while (ch=='y')
{
cout<<"请输入第一个复数的实部:"<<endl;
cin>>zr;
cout<<"请输入第一个复数的虚部:"<<endl;
cin>>zi;
zc1.setvalues(zr,zi);
cout<<"请输入第二个复数的实部:"<<endl;
cin>>zr;
cout<<"请输入第二个复数的虚部:"<<endl;
cin>>zi;
zc2.setvalues(zr,zi);
cout<<"两数相加请输入a,两数相减请输入s:"<<endl;
cin>>add_or_sub;
if (add_or_sub=='a')
{
zc3=zc3.Add(zc1,zc2);
}
if (add_or_sub=='s')
{
zc3=zc3.Substract(zc1,zc2);
}

zc3.print();
cout<<"要继续计算吗?请输入[Y] or [N]"<<endl;
cin>>ch;
}
}


为什么会出错呢？

太长了，没有编译器!
