Create and test a class called Points2. This class describes a sequence of 2D points. For example (1, 3), (4, 5) is a sequence of two points, where each coordinate is an integer. (1.2, 3.4), (5.6, 10.1), (11.1, 12.0) is a sequence of three points where each coordinate is a double. A sequence can have any size. An empty sequence has size 0.

Please fill out the code. To make things easier I will provide the file to input and the main file that will be used to test it. Please just stick with these funcstions that I have written out.

Please just help me with filling out the whole class(points2.h file)

Thank you.

points2.h file

#ifndef CSCI335_HOMEWORK1_POINTS2_H_ #define CSCI335_HOMEWORK1_POINTS2_H_

#include #include #include #include #include

namespace teaching_project { // Place comments that provide a brief explanation of the class, // and its sample usage. template class Points2 { public: // Default "big five" -- you have to alter them for your assignment. // That means that you will remove the "= default" statement. // and you will provide an implementation.

// Zero-parameter constructor. // Set size to 0. Points2() = default;

// Copy-constructor. Points2(const Points2 &rhs) = default;

// Copy-assignment. If you have already written // the copy-constructor and the move-constructor // you can just use: // { // Points2 copy = rhs; // std::swap(*this, copy); // return *this; // } Points2& operator=(const Points2 &rhs) = default;

// Move-constructor. Points2(Points2 &&rhs) = default;

// Move-assignment. // Just use std::swap() for all variables. Points2& operator=(Points2 &&rhs) = default;

~Points2() = default;

// End of big-five.

// One parameter constructor. Points2(const std::array& item) { // Provide code. }

// Read a chain from standard input. void ReadPoints2() { // Part of code included (without error checking). std::string input_line; std::getline(std::cin, input_line); std::stringstream input_stream(input_line); if (input_line.empty()) return; // Read size of sequence (an integer). int size_of_sequence; input_stream >> size_of_sequence; // Allocate space for sequence. // Add code here. Object token; for (int i = 0 ;input_stream >> token; ++i) { // Read coordinates. // Fill sequence_ here. } }

size_t size() const { // Code missing. }

// @location: an index to a location in the sequence. // @returns the point at @location. // const version. // abort() if out-of-range. const std::array& operator[](size_t location) const { // Code missing. }

// @c1: A sequence. // @c2: A second sequence. // @return their sum. If the sequences are not of the same size, append the // result with the remaining part of the larger sequence. friend Points2 operator+(const Points2 &c1, const Points2 &c2) { // Code missing. }

// Overloading the << operator. friend std::ostream &operator<<(std::ostream &out, const Points2 &some_points2) { // Code missing. } private: // Sequence of points. std::array *sequence_; // Size of sequence. size_t size_;

};

} // namespace teaching_project #endif

This would be the sequence to input.

3 7 4 3 5 19 71 4 100 101 2 3 40 50 11 33 3 2.1 20.3 11.11 12.45 13.1 14.2 2 1.1 100.0 20.1 30.2

And the following functions I have written to test the code.

// Do not change this file #include

#include #include #include using namespace std; using namespace teaching_project;

// Place stand-alone function in unnamed namespace. namespace { void TestPart1() { Points2 a, b; // Two empty Points2 are created. cout << a.size() << " " << b.size() << endl; // yields 0 0. const array a_point2{{7, 10}}; Points2 d{a_point2}; // A Points2 containing (7, 10) should be created. cout << d; // Should just print (7, 10). cout << "Enter a sequence of points (integer)" << endl; a.ReadPoints2(); // User enters a set of points in the form: // 3 7 4 3 2 1 10 // 3 specifies number of points. Points are the pairs // (7, 4) (3, 2) and (1, 10).*/ cout << "Output1: " << endl; cout << a; // Output should be what user entered. cout << "Enter a sequence of points (integer)" << endl; b.ReadPoints2(); // Enter another sequence. cout << "Output2: " << endl; cout << b; Points2 c{a}; // Calls copy constructor for c. cout << "After copy constructor1 c{a}: " << endl; cout << c; cout << a; a = b; // Should call the copy assignment operator for a. cout << "After assignment a = b" << endl; cout << a; Points2 e = move(c); // Move constructor for d. cout << "After e = move(c) " << endl; cout << e; cout << c; cout << "After a = move(e) " << endl; a = move(e); // Move assignment operator for a. cout << a; cout << e; } void TestPart2() { Points2 a, b; cout << "Enter a sequence of points (double)" << endl; a.ReadPoints2(); // User provides input for Points2 a. cout << a; cout << "Enter a sequence of points (double)" << endl; b.ReadPoints2(); // User provides input for Points2 b. cout << b << endl; cout << "Result of a + b" << endl; cout << a + b << endl; Points2 d = a + b; cout << "Result of d = a + b" << endl; cout << d; cout << "Second element in a: " << endl; cout << a[1][0] << ", " << a[1][1] << endl; // Should print the 2nd element. } } // namespace

int main(int argc, char **argv) { TestPart1(); TestPart2(); return 0; }

Thank you. Please help me with this question and filling out the class!
