- There should be a file for each. One file for EACH class(2 files), their function files (2 files) and a main file(1 file). In total, 5 files and its a class not a struct.PROGRAMMING LANGUAGE: C++ Write a program which has a class named FileHandlerto read StudentName, MarksObtained from the attached picture. The class should have a function which calculates grade for a student and then adds it in a new column i.e. Grade. The grade should be calculated considering the following criteria. A: 87-100, B+: 80-86, B: 72-79, C+: 66-71, C: 60-65, D: 50-59, F: 0-49 The file should be saved once grade for all students is calculated. Write the driver program for executing the task.C++You will create a header file with implementation that performs the task. Together with the header and implementation, you create a test program whose main function demonstrates that your functions work as they should. A file contains integers. You must write a function that show whether the integers in the file are in order or not. The test program should give output if a file with digits is sorted or not.. Try to come up with a method on your own before looking the algorithm. Input : file contains numeric values Output :The File is sorted Note : This algorithm you can use it: a ← read Value from the file while not End Of File (eof) implements b ← read Value from the file if a> b then return false end if a ← b end while return true (Algorithm decide if a file is sorted)
- Please read properly do not just send back random code that has nothing to do with what I need cuz that is not helpful My question below 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). The function called readEmpFromFile this function is different and should not to be mistaken with the function called readEmployee Each of these functions does something different than one another 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).,…Create a class Student that contains three members: roll no, name and mark, and threefunctions. Write a first inputStudent() function to get data of student class. Write a secondgetMark() function that returns a student’s mark. Write a third display() function thatdisplays a student’s data. In a main() function, you need to declare 40 students and get dataof all students by using inputStudent() function. And also use a pointer array to keep allstudents by mark greater than 50 and display the searching data of each student in thatpointer array (Use the access operator -> to access a pointer points to member functions ofthe Student class)C++ Create a class Student that contains three members: roll no, name and mark, and three functions.

- (FRP7) Write a function that reads data from a file. The file has already been opened and verified. The data should be saved in the array of type ship. The size of the array is passed in the int parameter and the number of records read is return in the last parameter, by reference. The file should be read until end of file has been reached or the array is full. struct ship{ string shipCaptain; string shipName; }; The function prototype isvoid readFile( ifstream&, ship[ ], int, int& ); ifstream - The already open file ship[ ] - array of structs where the data from the file will be stored. int - the size of the array. int& - the number of records read from the file. This value is set by the function before returning return- the number of records read from the file, returned by the function. The amount of data in the file is unknown but there is no bad data. The file format is the shipsName followed by the shipsCaptiain . Example: MillenniumFalcon HansSoloPlot Mean, Variance and Standard Deviation using matplotlib.2.a. Write a class with name EmployeeInfo that will keep track of employees name,salary, post, and joining year. Create a text file with information of five employeesof a company. Each row in the file should contain four columns. Read this filewith python and using the EmployeeInfo class, find out the employee with highestsalary and also find out the employee with longer time with company.b. Using the EmployeeInfo class and the same file, sort the employees in ascendingorder of salary using list’s functions.#function read file and display reportdef displayAverage(fileName):#open the fileinfile = open(fileName, "r")#variable declaration and initializationtotal = 0count = 0#read filefor num in infile:total = total + float(num)count = count + 1#close the fileinfile.close()#calculate averageaverage = total / count#display the resultprint("Average {:.1f}".format(average)) #method callingdisplayAverage("numbers.txt")
