Q1) Filtering FilesAssume the information of all the TAs for the ECE department is stored in a file that is called TAs.txt.In order to be eligible for the TA position, a student should be currently registered (i.e. not be an alumni).However, the file contains old data; it includes some records of TAs who have already graduated andwho are no longer allowed to TA. The format of each TA record in the file is as follows:StatusFirst NameThe first line of the file should show the total number of students records (max number of records is 100,you don't need to check for going over).Note that the TAs can be classified as any of the following (even if they don't all appear in your example):• Grad. UGradAlumPart A)You need to write a program that reads the file, removes any lines with invalid TAs (those who haveAlum as the value for classification) and updates the original file in the same format, just having removedinvalid TAS.Work with a vector of TA objects.Example 1Initial Student File:6Grad Shawn 3927320 MIAE 6Alum Nick 4386508 CSSE 7Alum John 96320753 ECE 10Alum Kate 52935193 MIAE 8Alum You3193 MIAE 5Alum Charles 0827261 BCEE 11After Correction:1Grad Shawn 3927320 MIAE 6Part B)Student Id Dept Working HoursImplement a function addNewTA () that prompts the user for the information representing one TA. Whena user selects 1, ask the user to enter new TAS: TA information should be entered in the same order asthe fields are stored in the file:Status First_Name Student Id Dept Working HoursPlease enter TA information separated by tabs to avoid confusion when parsing.Adding a TA in this manner should add the TA into the existing file. However, if a user enters a TAwith a Student Id that is already in the file, the program should reject the input and keep looping untila new Student Id is entered (but not entering the other data, that should be remembered).Your program should handle any exceptions (or other problems) if the user tries to enter information ofan unexpected type, like a string for the Student Id.Here is an example of how to handle an exception in C++:7 int main() {8 std::string input;910111213141516171819 }std::cout << "Enter an integer: ";try {std::getline (std::cin, input);int numberstd::stoi (input);std::cout << "You entered " << number << std::endl;} catch (const std::invalid_argument& e) {std::cerr << "Error: " << e. what () << " is not a valid integer.\n";} catch (const std::out_of_range& e) {std::cerr << "Error: " << e. what () << " is out of range.\n";Figure 1: Handling an exception in C++Note: This menu should be offered after the original behavior from Part A is complete. When the userselects a menu item, that functionality should complete before returning to the menu. Part C)Extend your TA record management system to offer a new option. If the user enters a 2, they should beprompted to select from a list of columns to order by, and then choose to order in ascending or descendingorder. The new ordering should be written out to the file in the same format as before.To accomplish this, use the TA class you implemented in the previous part of the assignment, and storeyour TA instances in a vector. Then, use the sort function from the C++ algorithm library to performthe sorting. Make sure your compiler is set to use at least C++11 so that you can use lambdas in yoursort function.When sorting the TAs, be careful to ensure that strings are ordered as strings and numbers are orderedas numbers (i.e. 10 should not end up before 2). Consult the sort function documentation for guidanceon how to accomplish this.Here is an example of how to use the sort function with a lambda to sort a vector of integers indescending order:21 std::vector vec{5, 2, 8, 1, 6};222324std::sort (vec.begin(), vec.end(), [] (int a, int b) {return a > b;});Figure 2: Using sort function with a lambda to sort a vector of integers in descending order
