Output

Certainly! To achieve this functionality in C++, we need to define a chainable set of classes that allow for the operations to be performed in a sequence. Below is an implementation that meets your requirements:

#include <iostream>

class Context {
public:
    int value;
    Context(int v) : value(v) {}
};

class Const {
public:
    Const(int v) : value(v) {}
    Context operator>>(const Square&) const;
    Context operator>>(const Inc&) const;
    Context operator>>(const Print&) const;
private:
    int value;
};

class Square {
public:
    Context operator()(const Context& ctx) const {
        return Context(ctx.value * ctx.value);
    }
};

class Inc {
public:
    Context operator()(const Context& ctx) const {
        return Context(ctx.value + 1);
    }
};

class Print {
public:
    void operator()(const Context& ctx) const {
        std::cout << ctx.value << std::endl;
    }
};

// Enable chaining of operations
Context Const::operator>>(const Square& op) const {
    return op(Context(value));
}

Context Const::operator>>(const Inc& op) const {
    return op(Context(value));
}

    op(Context(value));
    return Context(value); // Return a dummy Context to keep the chaining syntax
}

Context operator>>(const Context& ctx, const Square& op) {
    return op(ctx);
}

Context operator>>(const Context& ctx, const Inc& op) {
    return op(ctx);
}

Context operator>>(const Context& ctx, const Print& op) {
    op(ctx);
    return ctx; // Return the same context to keep the chaining syntax
}

// Example usage
int main() {
    Const(5) >> Square() >> Inc() >> Inc() >> Print(); // Should print 27
    return 0;
}
### Explanation 1. **Context Class**: This class holds the current value and allows passing this value through the chain of operations. 2. **Const Class**: This class initializes the chain with a constant value. It also defines the `operator>>` to start chaining with the next operation (Square, Inc, or Print). 3. **Square Class**: This class squares the value. 4. **Inc Class**: This class increments the value by one. 5. **Print Class**: This class prints the current value to the screen. 6. **Operator Overloading**: The `operator>>` is overloaded in several places to facilitate chaining of operations with the appropriate context. ### Usage In the `main` function, `Const(5) >> Square() >> Inc() >> Inc() >> Print();` will execute the operations in sequence: - Start with 5, - Square it to get 25, - Increment to get 26, - Increment again to get 27, - Finally, print 27. This setup provides a clear and concise way to chain operations using operator overloading in C++.

Certainly! To achieve this, we need to create a chainable class structure in C++ that allows us to pass values through a series of operations similarly to how you described. Below is an example implementation of the `Const`, `Square`, `Inc`, and `Print` classes that enable this chaining:

#include <iostream>

// Base class for chainable operations
class Chainable {
public:
    virtual ~Chainable() = default;
    virtual void execute(int& value) const = 0;
    Chainable* next = nullptr;

    Chainable& operator>>(Chainable& nextChain) {
        this->next = &nextChain;
        return nextChain;
    }

    void process(int value) const {
        execute(value);
        if (next) {
            next->process(value);
        }
    }
};

// Const class to initialize the value
class Const : public Chainable {
public:
    Const(int value) : initialValue(value) {}
    
    void execute(int& value) const override {
        value = initialValue;
    }

private:
    int initialValue;
};

// Square class to square the value
class Square : public Chainable {
public:
    void execute(int& value) const override {
        value *= value;
    }
};

// Inc class to increment the value
class Inc : public Chainable {
public:
    void execute(int& value) const override {
        value += 1;
    }
};

// Print class to print the value
class Print : public Chainable {
public:
    void execute(int& value) const override {
        std::cout << value << std::endl;
    }
};

int main() {
    Const(5) >> Square() >> Inc() >> Inc() >> Print();
    return 0;
}
In this implementation: 1. **Chainable Base Class**: This abstract class defines a common interface for all chainable operations and includes a mechanism to link operations together. 2. **Const Class**: This class initializes the value. 3. **Square Class**: This class squares the value. 4. **Inc Class**: This class increments the value. 5. **Print Class**: This class prints the value. The `operator>>` is overloaded to link the operations together. The `process` method is used to start the chain of operations. ### How to Use It: In the `main` function, you can chain the operations as follows: 
1
2
3
4
int main() {
    Const(5) >> Square() >> Inc() >> Inc() >> Print();
    return 0;
}
This will print `27` to the screen as expected (`5` squared is `25`, incremented twice becomes `27`).

### Explanation 1. **Base Class `Chainable`**: - This is an abstract base class with a pure virtual function `apply` which will be overridden by derived classes. 2. **Class `Const`**: - This class stores an initial constant value. - The `apply` method sets this value to the input reference. 3. **Class `Square`**: - This class squares the input value. - The `apply` method multiplies the input reference by itself. 4. **Class `Inc`**: - This class increments the input value. - The `apply` method increments the input reference by 1. 5. **Class `Print`**: - This class prints the input value. - The `apply` method outputs the input reference to the console. 6. **Operator Overloading**: - The `>>` operator is overloaded to accept two `Chainable` objects. It applies the left-hand side operation first, then the right-hand side operation. ### How it works: - **Const(5)** initializes the value to 5. - **Square()** squares it to 25. - **Inc()** increments it to 26. - **Inc()** increments it again to 27. - **Print()** prints the final value, which is 27. When you run the `main` function, it will output `27` as expected. ### Note: This implementation assumes that the `apply` method will be called in sequence, and it modifies a single integer value through the chain of operations. This is a simple and straightforward way to achieve the chaining of operations in C++.

Sure! To achieve this, you need to create a class chain that supports the operations `Const`, `Square`, `Inc`, and `Print`. Each class will perform a specific operation and then pass the result to the next class in the chain. Here's a way to implement this in C++:

Explanation: 1. **Const Class**: Stores the initial integer value. The `getValue()` method returns this value. 2. **Square Class**: Squares the given integer value. 3. **Inc Class**: Increments the given integer value by 1. 4. **Print Class**: Prints the given integer value to the console. 5. **Operator Overloads**: Overloads the `>>` operator to facilitate chaining operations. Each overload returns a functor that can be called with the initial value. 6. **Utility Function**: A generic `operator>>` function template to handle chaining of operations. In the `main` function, the expression `Const(5) >> Square() >> Inc() >> Inc() >> Print()` constructs a chain of operations that first squares the value, then increments it twice, and finally prints it. The result is that the value 27 gets printed to the screen.

Sure! To achieve this, we need to create a series of C++ classes that can be chained together using the `>>` operator. These classes will perform the following operations: 1. `Const` will initialize a value. 2. `Square` will square the current value. 3. `Inc` will increment the current value by 1. 4. `Print` will print the current value.

Explanation: 1. **Base Class `Chainable`:** This abstract class holds a protected integer value and a virtual function `next()` that is overridden by derived classes to perform their respective operations. 2. **Class `Const`:** This class initializes the integer value. It inherits from `Chainable` and passes the initial value to the base class constructor. 3. **Class `Square`:** This class squares the integer value. The `next()` function overrides the base class function to perform the squaring operation. 4. **Class `Inc`:** This class increments the integer value by 1. The `next()` function overrides the base class function to perform the increment operation. 5. **Class `Print`:** This class prints the integer value. The `next()` function overrides the base class function to print the value. 6. **Operator `>>`:** Each class has an overloaded `operator>>` to chain the operations together. The operator assigns the current value to the next object and calls its `next()` function. When you run the `main` function with `Const(5) >> Square() >> Inc() >> Inc() >> Print();`, it will output `27` as expected. Note: Remember to compile with a C++11 or later compiler to handle the initialization correctly.
