please help. where there are // is where code needs to be written please help. Don't ask for better pictures this is the best they will get just enlarge them and you should be able to read them. thanks for any and all help

The file coursedata.txt, located in the folder Data on the ca drive, contains information on CSIT course enrollments for a certain semester. The data looks like this: CSIT 104 Decker 26 CSIT 104 02 Decker 24 CSIT 473 01 Nazarenko CSIT 999 01 The data is organized into records. Each record contains the information for one course section, and includes, on separate lines: (I) the subject code and course number; (2) the section number: 3) the instructor's last name; (4) the enrollment for that section. Important: The records are ordered by course number, and the file ends with a "dummy record" for the nonexistent course, CSIT 999. Write a program to read the file and produce a report, showing the number of sections and total enrollment for each course. This report should be written to the file enrollment data, located in the Data folder on the C: drive. Here is a sample of what this report might look like: CSIT 104 74 24 CSIT 473 19

#include <fstream>
#include <string>
#include <iostream>
#include <stdlib.h>
#include <windows.h>

using namespace std;

int main()
{
ifstream input("C:\coursedata.txt");
string next, current, line;
  
if (!input.is_open()) {
cout << "unable to open input file" << endl;
exit(0);
}
  
if(!CreateDirectory("C:\Data", NULL) && ERROR_ALREADY_EXISTS != GetLastError())
{
cout << "Unable to create directory C:/Data" << endl;
exit(0);
}
  
ofstream output("C:\Data\enrollmentdata.txt");

if (!output.is_open()) {
cout << "unable to open output file" << endl;
exit(0);
}
  
int count=0, total=0;
  
if(std::getline(input, current)) {
std::getline(input, line); // for section number
count++;
std::getline(input, line); // ignore instructor
std::getline(input, line);
total = atoi(line.c_str());
while (std::getline(input, next))
{
  
if(next != current) {
output << current << endl;
output << count << endl;
output << total << endl;
  
// reset count
count = 0;
total = 0;
current = next;
}
  
std::getline(input, line); // for section number
count++;
std::getline(input, line); // ignore instructor
std::getline(input, line);
total += atoi(line.c_str());
}
cout << "Done" << endl;
  
} else {
cout << "No records in the file" << endl;
}
}
