Chapter 15, Problem 5PC
File Filter
A file filter reads an input file, transforms it in some way, and writes the results to an output file. Write an abstract file filter class that defines a pure virtual function for transforming a character. Create one subclass of your file filter class that performs encryption, another that transforms a file to all uppercase, and another that creates an unchanged copy of the original file.
The class should have a member function
void doFilter(ifstream &in, ofstream &out)
that is called to perform the actual filtering. The member function for transforming a single character should have the prototype
char transform(char ch)
The encryption class should have a constructor that takes an integer as an argument and uses it as the encryption key.

Assessment Description
Honors Students: Complete this assignment according to the directions provided in the "Honors Addendum," located in Class Resources.
This activity has multiple parts. All parts must be completed prior to documentation submission.
Part 1: Reading and Writing Text Files.
In this activity, you will learn how to read and write text files using non buffered and buffered File I/O classes, then learn how to parse a String into tokens using the String split() method, and finally, how to handle exceptions using various approaches.
Part 2: Reading and Writing JSON Files.
In this activity, you will learn how to read, write, and serialize JSON files to and from Java Objects.
Refer to the instructions within "Activity 4 Guide" to complete the assignment.
APA style is not required, but solid academic writing is expected.
This assignment uses a rubric. Please review the rubric prior to beginning the assignment to become familiar with the expectations for successful…
In C++ code:
Design and write a C++ class that reads text, binary and csv files. The class functions:
Size: Returns the file sizeName: Returns the file nameRaw: Returns the unparsed raw dataParse: A external function to Parse the data. The function accepts the raw data and returns the data parsed by the function. This type of function is called a "Call-Back Function". A Call-Back is necessary for each file as each file requires different regular expressions to parse.
Call-back.cpp
#include <string>#include <functional>#include <iostream>#include <vector>using namespace std;
string ToLower(string s){ string temp; for (char c : s) temp.push_back(tolower(c)); temp.push_back(NULL); return temp;}

EmpFromFile
Implement a function readEmpFromFile that takes a FILE * as the only argument and returns a pointer to a struct employee. This function should read the information from the file (reversing what writeEmpToFile does), create a new employee and fill in the data. If the FILE has no more info (is at end of file), this function should return NULL. This function must also ensure any employee actually created (not the NULL) is added to the array (as is done in createEmployee).
Change main to load employees from a file using a command called LOAD which is given to the program using (using your readEmpFromFile function you just wrote).
void main(void) {
int end = 1;
char * command;
char buff[256];

The students’ IDs and test answers are stored in a file. The first entry of the file contains the answer to the test in the form: TTFTFTTTFTFTFFTTFTTF Every other entry in the file is the student’s ID, followed by a blank, followed by the students’ response. For instance, the entry: ABC54102 T FTFTFTTTFTTFTTF TF The student’s ID is ABC54102, answer to question 1 is True, the answer to question 3 is False. Also, the student did not answer question 2 and question 18. The exam has 20 questions. Here is the grading policy: each correct answer is awarded two points, each wrong answer get -1 point, and no answer gets 0 point. Write a program that processes the test data. The output should be the student’s ID, followed by the answers, followed by the test score (total points), followed by the test grade.

Define a class called "EV", that represents the information of an electric vehicle. The EV is defined with these attributes: model (string), range(int), unit (string) and year (int). Functions of the EV class must perform the following operations: 1. A default constructor which sets all the numeric instance variables to zero. 2. A constructor with 4 parameters which sets the 4 instance variables to the corresponding values passed. 3. Implement a getter function for each of the 4 instance variables that will return the value of the instance variable. For example, the getX() function for the instance variable model must be called getModel(). 4.
