Explanation / Answer

1.

#include <type_traits>

#include <iostream>

template <typename T>

T foo(T && t,

    typename std::enable_if<std::is_same<T,int>::value, void **>::type = nullptr)

{

    std::cout << "Doubling " << t << " gives " << (t + t) << std::endl;

    return t + t;

}

template <typename T>

T foo(T && t, typename std::enable_if<!std::is_same<T,int>::value, void **>::type = nullptr)

{

    std::cout << "Squaring " << t << " gives " << (t * t) << std::endl;

    return t * t;

}

using namespace std;

int main()

{

    cout << foo(2) << endl;

    cout << foo(3.3) << endl;

    return 0;

}

2.

#include <iostream>

using namespace std;

template <class T>

inline T square(T x)

{

   T result;

   result = x * x;

   return result;

};

main()

{

   int    i, ii;

   float x, xx;

   double y, yy;

   i = 2;

   x = 2.2;

   y = 2.2;

   ii = square<int>(i);

   cout << i << ": " << ii << endl;

   xx = square<float>(x);

   cout << x << ": " << xx << endl;

   // Explicit use of template

yy = square<double>(y);

   cout << y << ": " << yy << endl;

   // Implicit use of template

   yy = square(y);

   cout << y << ": " << yy << endl;

}
