#include <iostream>
#include <sstream>
#include <stream>

template <typename T>
std::string to_string(const T& value)
{
std:stringstream oss;
oss << value;
return oss.str();
}

int main()
{
std::string s1(to_string(42));
std::string s2(to_string(3.14f));

std::cout << s1 << '\n'
<< s2 << '\n';

return 0;
}
