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

#include <iostream>
using namespace std;
template <class T>
inline T square(T x)
{
    T result;
    result = x * x;
    return result;
};
template <>
string square<string>(string ss)
{
    return (ss+ss);
};
int main()     
{
    int i = 4, ii;
    string ww("A");
    ii = square<int>(i);
    cout << i << ii;
    cout << square<string>(ww) << endl;
}
