Using Partial Template Specialization with class

Demo Code

#include <iostream>

using namespace std;

class MyClass/*from ww  w.ja v a2s.com*/
{
private:
    int m_Value{ 0 };

public:
    MyClass() = default;

    MyClass(int value)
        : m_Value{ value }
    {

    }

    MyClass(int number1, int number2)
        : m_Value{ number1 + number2 }
    {

    }
    int GetValue() const
    {
        return m_Value;
    }
};

template <typename T>
T Add(const T& a, const T& b)
{
    return a + b;
}

template <>
MyClass Add(const MyClass& myClass1, const MyClass& myClass2)
{
    return MyClass(myClass1.GetValue(), myClass2.GetValue());
}

template <typename T>
void Print(const T& value1, const T& value2, const T& result)
{
    cout << "The result of adding" << endl;
    cout << value1 << endl;
    cout << "to" << endl;
    cout << value2 << endl;
    cout << "is" << endl;
    cout << result;

    cout << endl << endl;
}

template <>
void Print(const MyClass& value1, const MyClass& value2, const MyClass& result)
{
    cout << "The result of adding" << endl;
    cout << value1.GetValue() << endl;
    cout << "to" << endl;
    cout << value2.GetValue() << endl;
    cout << "is" << endl;
    cout << result.GetValue();

    cout << endl << endl;
}

int main(int argc, char* argv[])
{
    const MyClass number1{ 1 };
    const MyClass number2{ 2 };
    const MyClass intResult{ Add(number1, number2) };
    Print(number1, number2, intResult);

    return 0;
}
