What will be the output of the following C++ code?

#include <iostream>
#include <string>
using namespace std;
template<typename T>
void print_mydata(T output)
{
    cout << output << endl;
}
int main()
{
    double d = 5.5;
    string s("Hello World");
    print_mydata( d );
    print_mydata( s );
    return 0;
}
