Transcribed Image Text:Introduction In this project, you will complete a C++ class by writing a copy constructor, destructor, and assignment operator. Furthermore, you will write a tester class and a test program and use Valgrind to check that your program is free of memory leaks. Finally, you will submit your project files on GL. If you have submitted programs on GL using shared directories (instead of the submit command), then the submission steps should be familiar. In this project we develop an application which holds the information about a digital art piece. There are two classes in this project. • The Random class generates data. The implementation of this class is provided. It generates random int numbers for colors. To create an object of this class we need to specify min and max values for the constructor. The colors fall between 30 and 37 inclusively. The Art class generates random colors and stores the color values. You implement the Art class. An object of the Art class is a digital masterpiece. The class stores the color values for every part of the masterpiece in a cell of a 2D array. The following figure presents multiple examples of a masterpiece presentation. The following figure represents the main data structure in this project. It is a 2d structure. Assignment Step 1: Create your working directory Create a directory in your GL account to contain your project files. For example, cs341/projo. Step 2: Copy the project files You can right-click on the file linkes on this page and save-as in your computer. Then, transfer the files to your GL account using SFTP. For this project, you are provided with the skeleton .h and.cpp files, a sample driver, and the output of driver program: . art.h - The interface for all Random and Art classes. art.cpp -The skeleton for the Art class implementation. driver.cpp - The sample driver/test program. driver.pdf - The output of sample driver/test program. Step 3: Complete the Art class The Art class has three data members. The member variable m_masterPiece holds a pointer to an array of pointers to multiple arrays. The class needs to allocate required memory dynamically. Every cell in this 2d structure holds an int number which represents a color code. The member variable m_numRows and m_numColumns define the size of the masterpiece. The variable m_numRows defines the height and the variable m_numColumns defines the width of the object. Art:Art() This is the default constructor. It creates an empty object. An empty object does not hold any memory. The constructor must initialize all member variables. The empty object has zero height and width. Art::Art(int rows, int columns) This is the constructor. It initializes all member variables and it allocates required memory if neccessary. If the user passes invalid parameters such a a negative size the constructor creates an empty object. Art: Art This is the destructor and it deallocates the memory. void Art:clear() This function deallocates all memory and reinitializes all member variables to default values. It clears

Transcribed Image Text:the current object to an empty object. void Art:create(int seed) This function generates random color code and inserts it into m_masterPiece. To generate random code the function must create a Random object initialized for generating int numbers. Please note, you do not modify the Random class. You only use the Random class. The parameter seed is the seed value to be used by the Random class. Art:Art(const Art& rhs) This is the copy constructor. It creates a deep copy of the rhs object. Deep copy means the new object has its own memory allocated. const Art& Art:operator=(const Art& rhs) This is the assignment operator. It creates a deep copy of rhs. Reminder: an assignment operator needs the protection against self-assignment. bool Art:appendToRight(const Art& rhs) This function appends the rhs object to the right of the current object. The append operation only happens if both objects have the same height or either object is empty. If the operation is successful the function returns true otherwise it returns false. The function allows for self-append, an object can be appended to the right of itself. Please note, appending requires reallocation of memory. bool Art:appendToBottom(const Art& bottom) This function appends the rhs object to the bottom of the current object. The append operation only happens if both objects have the same width or either object is empty. If the operation is successful the function returns true otherwise it returns false. The function allows for self-append, an object can be appended to the bottom of itself. Please note, appending requires reallocation of memory. void Art::dumpColors(string pixel) This function prints the object to the standard output. The implementation of this function is provided. You do not need to modify this function. This function is for debugging purposes. The parameter pixel is the character or the string that will be printed. Using a utf-8 character such as "\u2588" can create interesting effects. If you are using a Windows computer for development you can use ASCII characters such as "#"since Windows shell does not support utf-8 by default. The File windows.pdf provides instruction to activate the support of UTF characters. void Art:dumpValues() This function prints the color codes to the standard output. The implementation of this function is provided. You do not need to modify this function. This function is for debugging purposes. Step 4: Test your code The sample driver.cpp file will not be accepted as a test file. . The name of the test file must be mytest.cpp. The mytest.cpp file contains the Tester class, and the main function. . The test cases must be implemented in the Tester class, and must be called in the main function. . Every test function returns true or false to indicate the pass or fail. . A dump() function is provided for debugging purposes, visual inspections will not be accepted as test cases. You must write and submit a test program along with the implementation of the Art class. To test your Art class, you implement your test functions in the Tester class. The Tester class resides in your test file. You name your test file mytest.cpp. It is strongly recommended that you read the testing guidelines before writing test cases. A sample test program including Tester class, and sample test functions are provided in driver.cpp. You add your Tester class, test functions and test cases to mytest.cpp. You must write a separate function for every test case. Any program should be adequately tested. Adequate testing includes testing the functionaly for normal cases, edge cases and error cases. The following list presents some examples:
