#include <iostream>
#include <fstream>
#include <string>
#include <sstream>
using namespace std;
template <class T>
string to_string(T t, ios_base & (*f)(ios_base&))
{
ostringstream oss;
oss << f << t;
return oss.str();
}
int main ()
{
int integer;
cout << "Enter A Number To Conver Into Hex=" ;
cin>>integer;
cout << endl;
cout<<"Hex Output="<<to_string<long>(integer, hex)<<endl;
return 0;
}
OUTPUT:
