Output

To achieve the desired effect in C++, you can design a series of classes that each overload the `operator>>` to chain operations together. Here's how you can implement this:

#include <iostream>

class Print {
public:
    Print(int value) : value(value) {}
    void operator()() const {
        std::cout << value << std::endl;
    }
private:
    int value;
};

class Inc {
public:
    Inc(int value) : value(value) {}
    Print operator>>() const {
        return Print(value + 1);
    }
private:
    int value;
};

class Square {
public:
    Square(int value) : value(value) {}
    Inc operator>>() const {
        return Inc(value * value);
    }
private:
    int value;
};

class Const {
public:
    Const(int value) : value(value) {}
    Square operator>>() const {
        return Square(value);
    }
private:
    int value;
};

int main() {
    Const(5) >> Square() >> Inc() >> Inc() >> Print()();
    return 0;
}
### Explanation: 1. **Const Class**: - Stores an initial integer value. - Overloads `operator>>` to return a `Square` object initialized with the stored value. 2. **Square Class**: - Stores an integer value. - Overloads `operator>>` to return an `Inc` object initialized with the square of the stored value. 3. **Inc Class**: - Stores an integer value. - Overloads `operator>>` to return a `Print` object initialized with the value incremented by 1. 4. **Print Class**: - Stores an integer value. - Overloads `operator()` to print the stored value. ### Usage: The `main` function demonstrates how these classes can be chained together to achieve the desired behavior. The sequence `Const(5) >> Square() >> Inc() >> Inc() >> Print()()` will output 27 to the screen. ### Output: When you run the program, it will print: 
1
27
This demonstrates the chaining of operations using the `operator>>` overload in C++.

### Explanation: 1. **Chain Class**: This is a base class with a pure virtual function `operator>>` to enable chaining of operations. 2. **Const Class**: Initializes the value and starts the chain. It implements the `operator>>` to pass the value to the next operation. 3. **Square Class**: Squares the value it receives and passes it to the next operation. 4. **Inc Class**: Increments the value it receives and passes it to the next operation. 5. **Print Class**: Prints the value it receives and ends the chain. The main function demonstrates how to use these classes to achieve the desired output. The sequence `Const(5) >> Square() >> Inc() >> Inc() >> Print()` will print `27` to the screen as expected.

### Explanation: 1. **Context Class**: This class holds the intermediate value as it is passed through the chain of operations. 2. **Const Class**: Initializes the value. 3. **Square Class**: Squares the value. 4. **Inc Class**: Increments the value. 5. **Print Class**: Prints the value. 6. **Operator Overloading**: The `>>` operator is overloaded to allow chaining of the operations. ### Execution: - `Const(5)` initializes the value to 5. - `>> Square` squares the value (5 * 5 = 25). - `>> Inc` increments the value (25 + 1 = 26). - `>> Inc` increments the value again (26 + 1 = 27). - `>> Print` prints the final value (27). When you run the program, it will output `27` to the screen.

Output

To achieve the desired functionality in C++, we can create a class `Const` that initializes with a value, followed by classes `Square`, `Inc`, and `Print` that can be chained together. We'll use operator overloading to allow the chaining (`>>` operator). Here's how you can write these classes in C++:

### Explanation: 1. **Base Class**: Defines the interface for the `operator>>` which will be overridden by derived classes. 2. **Const Class**: Initializes with a value and implements the `operator>>` for `Square`, `Inc`, and `Print`. 3. **Square Class**: Squares the value and implements the `operator>>` for `Inc` and `Print`. 4. **Inc Class**: Increments the value and implements the `operator>>` for `Inc` and `Print`. 5. **Print Class**: Prints the value and implements the `operator>>` for `Print`. ### Usage: In the `main` function, the chaining is demonstrated with `Const(5) >> Square() >> Inc() >> Inc() >> Print();`, which results in printing `27` to the screen. The value `5` is squared to `25`, then incremented twice to `27`, and finally printed.

### Explanation: 1. **Base Class**: This class holds the value and provides the interface for the `>>` operator and the `print` function. 2. **Const Class**: Initializes the value. When chained with another operation, it passes its value to the next operation. 3. **Square Class**: Squares the value it receives. When chained with another operation, it passes the squared value. 4. **Inc Class**: Increments the value it receives. When chained with another operation, it passes the incremented value. 5. **Print Class**: Prints the value it holds when the `print` function is called. ### Usage: The example `Const(5) >> new Square() >> new Inc() >> new Inc() >> new Print()->print();` demonstrates how the classes can be chained together to perform the desired operations sequentially. ### Note: - This implementation uses dynamic memory allocation (`new`) for each operation. Ensure proper memory management (deallocation) if you plan to use this in a larger application. - The `print` function is called at the end of the chain to display the final value.
