Add + and << operators to a class to work with template function

Demo Code

#include <iostream>

using namespace std;

class MyClass/*from  w  w  w . j a va 2s . com*/
{
    friend ostream& operator <<(ostream& os, const MyClass& myClass);

private:
    int m_Value{ 0 };

public:
    MyClass() = default;

    MyClass(int value): m_Value{ value }
    {
    }

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

    }

    MyClass operator +(const MyClass& other) const
    {
        return m_Value + other.m_Value;
    }
};

ostream& operator <<(ostream& os, const MyClass& myClass)
{
    os << myClass.m_Value;
    return os;
}

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

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;
}

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;
}

Result
