(c++)Read and parse the flat file, schedule.txt, lineby line, and find the term,section number,course,instructor,schedule, andsubject information.

[Part 1]

Copy and paste the first couple hundred lines into another textfile. Include a count variable to count how manylines read in. Display the classCode(term+ section) and course parsed from eachline, and the total number of lines processed. Make sure thesubjectCode is processed from thecourse string correctly.

[Part 2]

After complete part 1, use the original schedule.txt. Displaythe total number of lines processed.

Submission: The source file (LabExercise4.cpp) and sampleoutput

Given code:

#define _CRT_SECURE_NO_WARNINGS#include #include #include using namespace std;#include  // for strtok and strcpyint main(){  // for parsing the inputfile  char* token;  char buf[1000];  const char* const tab = "t";  // open the input file  ifstream fin;  fin.open("dvc-schedule.txt");  if (!fin.good())     cout << "I/O error.
