Recent Question/Assignment

I need the answer in modified points2d.h and README.txt where you state you have completed for each question.
CSCI 335
First programming assignment (100 points)
Due September 16
Please follow the blackboard instructions on writing and submitting programming assignments. It should compile to receive any credit.
Submit only the files requested in the deliverables at the bottom of this description to gradescope by the deadline.
Programming: The big five
Create and test a class called Points2D. 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.
The purpose of this assignment is to have you create a Points2D class from scratch with limited help from the STL. Since Points2D can have arbitrary size, you should use pointers. The private data members should be:
size_t size; std::array Object, 2 *sequence_;
Object is the template type parameter (i.e int, double, etc.). An initial piece of code with the structure of the class is provided. Do not change the data representation (for instance do not use a vector or list to represent the sequence_).
Pay special attention to Weisss -big five-, the destructor, copy constructor, copy assignment operator, move constructor and move assignment operator.
Included are the two files (points2d.h, test_points2d.cc) you will need, as well as the Makefile. Do not modify the Makefile or the file names. Do not modify the test_points2d.cc file except by changing or adding include files if needed. You can comment in the main file the parts you didn’t complete. The points2d.h file is not complete. In the file it is explained where to provide changes. I am also providing you with a sample input file test_input_file.txt and I am explaining how to use it at the end of this document.
This assignment will help you revisit constructors, destructors, overloading of operators, and templates. Follow a consistent C++ coding style, for instance https://google.github.io/styleguide/cppguide.html
PART 1 [70 points]
Implement the “big five”. Add the output stream operator.
Demonstrate that you are able to read and write correctly by including the following code in the main file. The code is already provided for you in the main file. You can comment parts of it as you are testing your implementation. For full credit all functions should work.
void TestPart1() {
Points2D int a, b; // Two empty Points2D are created.
cout a.size() - - b.size() endl; // yields 0 0.
const array int, 2 a_point2{{7, 10}};
Points2D int d{a_point2}; // Sequence (7, 10) should be created. cout d; // Should just print (7, 10)
cout -Enter a sequence of points (integer)- endl;
a.ReadPoints2D(); // 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.ReadPoints2D(); // Enter another sequence.
cout -Output2: - endl; cout b;
Points2D int 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;
Points2D int 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; }
PART 2 [30 points]
Overload the + and [] operators for your Points2D class. Test with the following code. The code is already provided for you in the main file. You can comment parts of it as you are testing your implementation. For full credit all functions should work.
void TestPart2() { Points2D double a, b; cout -Enter a sequence of points (double)- endl;
a.ReadPoints2D(); // User provides input for Points2D a.
cout a; cout -Enter a sequence of points (double)- endl;
b.ReadPoints2D(); // User provides input for Points2D b.
cout b endl; cout -Result of a + b- endl; cout a + b endl; Points2D double 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.
} // End of TestPart2
Do not send to the standard output anything else other what is asked. Do not pause for input, or interact with the user.
You can run the program as follows:
./test_points2d
In that case you should enter the required data in the standard input.
You can also run it as follows
./test_points2d test_input_file.txt
In that case the output should be the one contained in expected_output.txt
Note that the code for test_points2 is the same in both cases. In the second call the shell redirects the contents of test_input_file.txt to the standard input.
Deliverables to upload to gradescope for Assignment 1:
• Submit your modified points2d.h
• Submit single README.txt file where you state what you have completed for each question.
