Output

To achieve the desired functionality in C++, you can create classes `Const`, `Square`, `Inc`, and `Print` that overload the `>>` operator to chain operations together. Here's how you can implement it:

#include <iostream>

// Base class to hold the value
class ValueHolder {
protected:
    int value;
public:
    ValueHolder(int v) : value(v) {}
    int getValue() const { return value; }
};

// Const class to initialize the value
class Const : public ValueHolder {
public:
    Const(int v) : ValueHolder(v) {}
};

// Square class to square the value
class Square : public ValueHolder {
public:
    Square(const ValueHolder& vh) : ValueHolder(vh.getValue() * vh.getValue()) {}
};

// Inc class to increment the value
class Inc : public ValueHolder {
public:
    Inc(const ValueHolder& vh) : ValueHolder(vh.getValue() + 1) {}
};

// Print class to print the value
class Print {
public:
    Print(const ValueHolder& vh) {
        std::cout << vh.getValue() << std::endl;
    }
};

// Overload the >> operator for Const
Square operator>>(const Const& c, const Square&) {
    return Square(c);
}

// Overload the >> operator for Square
Inc operator>>(const Square& s, const Inc&) {
    return Inc(s);
}

// Overload the >> operator for Inc
Print operator>>(const Inc& i, const Print&) {
    return Print(i);
}

int main() {
    Const(5) >> Square() >> Inc() >> Inc() >> Print();
    return 0;
}
### Explanation: 1. **ValueHolder**: This is a base class that holds the integer value. It is inherited by other classes to access and modify the value. 2. **Const**: This class initializes the value. It takes an integer and stores it in the `ValueHolder`. 3. **Square**: This class squares the value. It takes a `ValueHolder` object, squares its value, and stores the result. 4. **Inc**: This class increments the value. It takes a `ValueHolder` object, increments its value by 1, and stores the result. 5. **Print**: This class prints the value. It takes a `ValueHolder` object and prints its value to the screen. 6. **Operator Overloading**: The `>>` operator is overloaded to chain the operations together. Each overloaded operator returns the next class in the chain. ### How it works: - `Const(5)` initializes the value to 5. - `Square()` squares the value, resulting in 25. - `Inc()` increments the value by 1, resulting in 26. - `Inc()` increments the value by 1 again, resulting in 27. - `Print()` prints the final value, which is 27. When you run the program, it will output `27` to the screen.
