很简单的一段代码，各位老大帮俺查查错，谢谢

[z33]

#include <iostream.h>
#include "shape.h"

void main()
{
int i,a,b,c;
while(1)
{
cout<<"1 圆"<<endl;
cout<<"2 矩"<<endl;
cout<<"3 方"<<endl;
cout<<"4 角"<<endl;
cout<<"5 平"<<endl;
cout<<"请选择：";
cin>>i;
while(i<1||i>5)
{
cout<<"错误，重新选择(1-5)：";
cin>>i;
}
cout<<endl;
switch(i)
{
case 1:
cout<<"半径：";
cin>>a;
Round ro(a);
cout<<endl;
cout<<"圆的半径为 "<<ro.Getr()<<endl;
cout<<"圆的周长为 "<<ro.Getzou()<<endl;
cout<<"圆的面积为 "<<ro.Getmain()<<endl;
cout<<ro.Getname()<<endl;
break;
case 2:
cout<<"长，宽：";
cin>>a,b;
Reg re(a,b);
cout<<"矩形的长为 "<<re.Getchang()<<endl;
cout<<"矩形的宽为 "<<re.Getkuan()<<endl;
cout<<"矩形的周长为 "<<re.Getzuo()<<endl;
cout<<"矩形的面积为 "<<re.Getmain()<<endl;
break;
case 3:
cout<<"边：";
cin>>a;
Square sq(a);
cout<<"正方的长为 "<<sq.Getchang()<<endl;
cout<<"正方的周长为 "<<sq.Getzuo()<<endl;
cout<<"正方的面积为 "<<sq.Getmain()<<endl;
break;
case 4:
cout<<"边一，边二，边三：";
cin>>a,b,c;
Tri tr(a,b,c);
cout<<"三角形周长："<<tr.Getzou()<<endl;
cout<<"三角形面积："<<tr.Getmain()<<endl;
break;
case 5:
cout<<"底，斜，高：";
cin>>a,b,c;
Ping pi(3,5,4);
cout<<"平形四边形周长："<<pi.Getzou()<<endl;
cout<<"平形四边形面积："<<pi.Getmain()<<endl;
}
}
}



错误如下：

把函數定義等
Round ro(a);
拿到case外。
case 5:

[gull1234]

Round ro(a);
switch(i)
{
case 1:
cout<<"半径：";
cin>>a;

cout<<endl;
cout<<"圆的半径为 "<<ro.Getr()<<endl;
cout<<"圆的周长为 "<<ro.Getzou()<<endl;
cout<<"圆的面积为 "<<ro.Getmain()<<endl;
cout<<ro.Getname()<<endl;
break;
