Question
ASAP Please
write this C++ program using
this task needs to be done with vector of TAs object. Please explain how does it work as I don't know anything about it. Any explanation and comment is very needed .
please don't copy from any other sources .please write on your own or skip.
PLEASE ATTACH PICTURES w te written code and show the output too Thank you so much for your time and help
Transcribed Image Text:Q1) Filtering Files
Assume 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 and can not be an
alumni. However, the file contains old data; it includes some records of TAs who have already graduated
and who are no longer allowed to TA. The format of each TA record in the file is as follows:
Student Id Working Hours Year Hired
Grad
• Ugrad
Alum
The first line of the file should show the total number of students records (max number of records is
100).
Note that the TAs can be classified as any of the following (even if they don't all appear in your example):
Initial Student File:
Part A)
You need to write a program that reads the file, removes any lines with invalid TAs (those who have
Alum as the value for classification) and updates the original file.
Work with a vector of TA objects.

- You must use one other model (math/random).arrow_forwardC++ I cannot run the code. Please help me fix it. Below is the requirement of the 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 data (use vector here to get the unparsed raw data)Parse: 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. With binary files, need to use RegEx to do the parse(). [My code doesn't have this part] Please refer to the Callback.cpp example on how to setup a Call-Back.
