雅典奥运会歌曲:懂一点点c++的帮忙

下面是一个演示c++异常处理机制的小程序，我照书上抄的，但是compile后有如下错误提示：--------------------Configuration: Cpp1 - Win32 Debug--------------------
Compiling...
Cpp1.cpp
C:\Documents and Settings\s1.C00\桌面\Cpp1.cpp(30) : error C2601: 'inputdata' : local function definitions are illegal

Error executing cl.exe.

Cpp1.obj - 2 error(s), 0 warning(s)
下面是源程序
#include <iostream.h>
#include <ctype.h>
int inputdata(void);
int main()
{
int value;
int continueflag=1;
cout<<"~~~exception handing~~~"<<endl;

}
catch (int zero){

}
catch (const char *message){
cerr<<message<<endl;
}
catch (...){

cout <<"end of my act !:-)";
return 0;
}

int inputdata(void)
{
int userdata;
cout<<"enter a number:";
cin>>userdata;
if (userdata==0)
throw 0;
else if (userdata<5)
throw("number is too low");
else if (userdata>15)
throw("number is too high");
return (userdata);
}
