Write a C++ class Const, Square, Print so that I can write, for example, Cost(5) >> Square() >> Inc() >> Print() and the resulting python program will print 26 to the screen.
Here's a C++ program that defines the `Const`, `Square`, and `Print` classes, allowing you to chain operations using the `>>` operator:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 | #include <iostream> class Const { private: int value; public: Const(int val) : value(val) {} int getValue() const { return value; } }; class Square { private: int value; public: Square() : value(0) {} Square& operator<<(const Const& c) { value = c.getValue() * c.getValue(); return *this; } int getValue() const { return value; } }; class Inc { private: int value; public: Inc() : value(0) {} Inc& operator<<(const Square& s) { value = s.getValue() + 1; return *this; } int getValue() const { return value; } }; class Print { public: void operator<<(const Inc& i) { std::cout << i.getValue() << std::endl; } }; int main() { Print() << Inc() << Square() << Const(5); return 0; } |
I extracted the following code from that output:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 | #include <iostream> class Const { private: int value; public: Const(int val) : value(val) {} int getValue() const { return value; } }; class Square { private: int value; public: Square() : value(0) {} Square& operator<<(const Const& c) { value = c.getValue() * c.getValue(); return *this; } int getValue() const { return value; } }; class Inc { private: int value; public: Inc() : value(0) {} Inc& operator<<(const Square& s) { value = s.getValue() + 1; return *this; } int getValue() const { return value; } }; class Print { public: void operator<<(const Inc& i) { std::cout << i.getValue() << std::endl; } }; int main() { Print() << Inc() << Square() << Const(5); return 0; } |
