Template problem ...

Hi all,
Need your help. I am doing a simple template program , getting some error ... here is the code

#include <iostream>
#include <stdio.h>
#include <stdlib.h>
#include<iostream>
#include<string>
#include <sstream>
using namespace std;
class Base_class
{
public:
Base_class(){ };
~Base_class(){ };
template <class T>
static int fun(T decimal_value,string& check)
{
ostringstream ostr;
ostr<<decimal_value<<endl;
string str=ostr.str();
check=str;
return 0;
}
};
int main()
{
try
{
string check;
int a=7777;
Base_class ::fun(a,check);
cout<<check<<endl;
double b=7777.9755;
Base_class::fun(b,check);
cout<<check<<endl;
char c[]="AMARTYA";
Base_class::fun(c,check);
cout<<check<<endl;
}
catch(...)
{
cout<<"Function Cutil::failed"<<endl;
}
return 0;
}

This code works fine ....
But i want the Definition of the function not in the main class , i want to put it outside function ......
If i do that ..... It is giving error .....
Please provide some solution(s)...

       class valarray< _Tp >

Detailed Description
   template<class _Tp>class std::slice_array< _Tp >
       Reference to one-dimensional subset of an array.

       A slice_array is a reference to the actual elements of an array specified by a slice. The way to get a slice_array is to call
       operator[](slice) on a valarray. The returned slice_array then permits carrying operations out on the referenced subset of elements in the
       original valarray. For example, operator+=(valarray) will add values to the subset of elements in the underlying valarray this slice_array
       refers to.

       Parameters:
	   Tp Element type.

       Definition at line 80 of file valarray.
