” CS 435编程语言写作、辅导C++程序CS 435/535 Assignment #5 Spring 2021Project Overview: This project investigates polymorphism in C++. In C++, polymorphism allows the mainfunction to be written before an actual class is defined. In this project, you will download from Blackboard the filemain.cpp that contains the main function and the two files (Shape.h and Shape.cpp) that define a baseclass named Shape. The Shape Base class has a name represented by a private instance variable called name, butit does not have any other details on the shape. However, the base class has four (4) pure virtual functions: getArea(it is supposed to compute the surface area of the shape), getVolume (to compute the volume of the shape), test(to test whether the shape satisfies a list of conditions), and getInfo (to form a string that describes the shape).You are asked to write four (4) derived classes: Sphere, Cylinder, Cone, and Cuboid. For detailed informationon these four particular shapes, please refer to httpss://www.mathsisfun.com/geometry/common-3d-shapes.html.The website also shows How to compute the surface area and the volume of these four shapes. The relationshipbetween the base class and these four derived classes is shown below. These four derived classes have added theirown instance variables to describe the details of the corresponding shapes. For each derived class, you need to haveone header file (with the .h extension) and one implementation file (with the .cpp extension). However, you canuse any name for the file, any name for the class, and any names for instance variables. The main function does notneed to know the class names you will use. The only requirement is that each derived class must be derived from theShape base class, which will force you to implement the four virtual functions in the derived class. Polymorphismenables the main function to invoke a function of a derived class in the future by just calling the corresponding virtual function of the baseclass.To test the program, we assume that the shapes will be stored in a data file that will be passed to the program as acommand line argument. Each shape will occupy one line in the data file. Each line starts with the name that is astring, followed by the type (sphere, cylinder, cone or cuboid). The rest will be doubles to represent thedimensions of the shape.name sphere radiusname cylinder radius heightname cone radius heightname cuboid length width heightYou can download a sample data file named shapes.dat from Blackboard for an example. It contains thefollowing shapes.Cube#1 cuboid 1 1 1Cube#2 cuboid 2 2 2Cone#1 cone 1 1Cyl#1 cylinder 1 1Box#1 cuboid 2 4 6Box#2 cuboid 10.5 21 10.5UnitSphere sphere 1LargeSphere sphere 100Cone#2 cone 1 2Cyl#2 cylinder 1 2You need to write a Function named readFrom that will return a pointer to a vector of shapes read from a data filewith its name given as a parameter to the function. The function has the following signature.std::vectorShape* *readFrom(std::string);The signature is stored in a file named reading.h that you can also download from Blackboard. You need to createa .cpp file to implement the function. You can assume a data file will always follow the correct format as describedabove. However, if the file cant be opened for reading, you shall return a pointer to an empty vector.As mentioned earlier, you need to implement four virtual functions in each of four derived classes. Please refer to thewebsite mentioned above on how to compute the surface area and the volume. For the getInfo function, pleasesee the sample execution at the end on how to format the output string. The test function is to test whether theshape satisfies a list of conditions. The list of conditions is passed to the function as a parameter and it is a vector ofstrings. The number of strings in the vector will always be a multiple of 3. Three consecutive strings form a testcondition in the name op value form. The name string will be type, area or volume. Theop string is one of the six relational operators (==, !=, =, =, , and ). The valuestring is the reference value in the string format to be compared with. For the test function to return true, all thetest conditions have to be satisfied. For example, if the string vector contains 9 strings: type cyl area= 1000 volume 100.5, the function returns true if the shape type is greater than cyl and thesurface area is less than or equal to 1000 and the volume is greater than 100.5. If the vector is empty (containing notesting conditions), the function will always return true. Please see the getTestConditions function inmain.cpp to see how to build a list of test conditions.In this project, you need to create a makefile to compile the program. Please use the Wall -std=c++11 optionswhen compiling your program with g++. The executable of this program shall be named as a.out regardless of theoperating system you are using (using the -o a.out option with g++). Your makefile shall support thecommands make to produce a.out, and make clean to remove a.out and any object files (with the .oextension).What You Need To Do Create a directory named project5 on your machine. Download main.cpp, Shape.h, Shape.cppreading.h, and shapes.dat from Blackboard to the project5 directory. You can make changesto shapes.dat for more testing, but make no changes to the other downloaded files. Add four (4) derived classes as required. Each class shall have its own header and implementation. You can addmore derived classes for additional shapes and the main function will work with them too without any changes. Create a .cpp file to implement the readFrom function, based on its signature in reading.h. Create a makefile that supports the commands make to produce a.out, and make clean toremove a.out and any object files. Your makefile will be used to compile your program to producea.out, and a.out will be used to test your program. When you are ready to submit your project, compress your project5 directory into a single (compressed)zip file, project5.zip. No other compressed files will be accepted. It is not necessary to include thefiles downloaded from Blackboard. Once you have a compressed zip file named project5.zip, submit that zip file to Blackboard. Your submission will be Graded on cs-parallel.ua.edu. Make sure to test it on that machine beforesubmission. Make sure to follow the above instructions exactly. Otherwise we may not be able to grade your submission.Assignment #5 is due at 11:59pm on Friday, March 19.
