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

#include <iostream>
using namespace std;
template<typename T> 
inline T square(T x)
{
    T result;
    result = x * x;
    return result;
};
int main()
{
    int i, ii;
    float x, xx;
    double y, yy;
    i = 2;
    x = 2.2;
    y = 2.2;
    ii = square(i);
    cout << i << " "  << ii << endl;
    yy = square(y);
   cout << y << " " << yy << endl;
}
