This probably has a really simple fix but I cant for the life of me see it. I have two input files one with courses and one with students. For students it parses data and adds the object into a list. I’m trying to get it so that when I go to output the student objects with similar data from the list (ex: Doe,John,1233485,ART Doe,John,1233485,MATH) it doesn’t output each object, but one object with cumulative data. (I don’t know if I’m explaining it the best sorry-)

`// Parse student data
while (getline(fileStudent, studentLine)) {

istringstream iss(studentLine);
string lastName, firstName, SID, courseList;

// Parse the CSV line
if (getline(iss, lastName, ',') && getline(iss, firstName, ',') &&
    getline(iss, SID, ',') && getline(iss, courseList)) {

    // Calculate total credit hours for the student
    int totalCreditHours = 0;

    // Iterate over the courses the student has requested
    istringstream courseStream(courseList);
    string courseName;

    while (getline(courseStream, courseName, ',')) {

        // Look up the course
        auto it = courses.find(Course(courseName, 0, 0, 0));

        if (it != courses.end()) {

            // Increment enrollment count for the course
            it->incrementEnrolled();

            // Add the student to the course roster
            Course& course = const_cast<Course&>(*it); // Remove const
            course.enrollStudent(SID);

            // Update total credit hours
            totalCreditHours += it->getCreditHours();
        }
    }

    // Create the student object and add it to the list
    Student student(lastName, firstName, SID, courseList, totalCreditHours);
    students.push_back(student);
}

}
fileStudent.close();`

I’ve tried altering my code several times to combat this. To no avail my program still outputs all of the similar objects not adding anything together.
