Program won't perform this if-branch [closed]

The objective of this program is to be able to change any of the following values using user input: department ID, course number, section, credits, instructor, days, time, max class enrollment, students and student IDs of said students enrolled, and registration status. You should be able to change any of those values and be able to print it all out in the end. Here is the part of my code with the issue:

cout << "Please input \"c\" if you want to make any changes." << endl;
    cin >> makeChanges;

    if (makeChanges == 'c') {
        cout << "Please input which change you would like to make: " << endl;
        cout << "Department ID" << endl;
        cout << "Course Number" << endl;
        cout << "Section" << endl;
        cout << "Credits" << endl;
        cout << "Instructor" << endl;
        cout << "Day(s)" << endl;
        cout << "Time" << endl;
        cout << "Campus" << endl;
        cout << "Building" << endl;
        cout << "Room Number" << endl;
        cout << "Max Class Enrollment" << endl;
        cout << "Students" << endl;
        cout << "Student IDs" << endl;
        cout << "Registration Status" << endl;
    }
    else {
        courseInfo.printInfo();
    }

    getline(cin, changeType);

    if (changeType == "Department ID") {
        cout << "Please input the department ID." << endl;
        getline(cin, department);
        courseInfo.setCourseID(department);
    }

    else if (changeType == "Course Number") {
        cout << "Please input the course number." << endl;
        cin >> classNum;
        courseInfo.setCourseNum(classNum);
    }

    else if (changeType == "Section") {
        cout << "Please input the section number." << endl;
        cin >> section;
        courseInfo.setSectNum(section);
    }

    else if (changeType == "Credits") {
        cout << "Please input the number of credits." << endl;
        cin >> credits;
        courseInfo.setNumCreds(credits);
    }

    else if (changeType == "Instructor") {
        cout << "Please input the instructor." << endl;
        getline(cin, professor);
        courseInfo.setInstructName(professor);
    }

    else if (changeType == "Day(s)") {
        cout << "Please input the day(s): M, T, W, Th, or F." << endl;
        getline(cin, days);
        courseInfo.setDays(days);
    }

    else if (changeType == "Time") {
        cout << "Please input the hour of the start time." << endl;
        cin >> hour1;
        courseInfo.setCourseHour1(hour1);

        cout << "Next please input the minutes of the start time (If it is 0, then put in 00)." << endl;
        cin >> min1;
        courseInfo.setCourseMinute1(min1);

        cout << "Please input the hour of the end time." << endl;
        cin >> hour2;
        courseInfo.setCourseHour2(hour2);

        cout << "Next please input the minutes of the end time (If it is 0, then put 00)." << endl;
        cin >> min2;
        courseInfo.setCourseMinute2(min2);
    }
    
    else if (changeType == "Campus") {
        cout << "Please input the campus your course is held on." << endl;
        getline(cin, campus);
        courseInfo.setCampus(campus);
    }

    else if (changeType == "Building") {
        cout << "Please input the building your course is held in." << endl;
        cin >> building;
        courseInfo.setClassroomBuilding(building);
    }

    else if (changeType == "Room Number") {
        cout << "Please input the classroom number." << endl;
        cin >> roomNum;
        courseInfo.setClassroomNum(roomNum);
    }

    else if (changeType == "Max Class Enrollment") {   
        cout << "Please input maximum students in the course." << endl;
        cin >> maxClass;
        courseInfo.setMaxEnroll(maxClass);
    }

    else if (changeType == "Students") {
        cout << "Please input the number of students enrolled." << endl;
        cin >> numStuds;
        courseInfo.setNumStuds(numStuds);
    }

    else if (changeType == "Student IDs") {
        cout << "Please input the IDs of each student enrolled." << endl;
        courseInfo.inputStudIDs(numStuds);
    }

    else if (changeType == "Registration Status") {
        cout << "Please input the registration status: \"o\" for open, \"c\" for close, or \"x\" for cancelled." << endl;
        cin >> status;
        courseInfo.setCourseStat(status);
    }
    courseInfo.printInfo();

When testing this by attempting to change any value that is more than one word (like Department ID), the program just outputs all of the initial values without following through with the if-branch and actually changing the value. However, this is not an issue for one-word values (like Section). What can I do to fix this error?

Edit: I already included directives and functions and their respective definitions, but they are too long to put here. It still compiles, but it just doesn't follow through with the if-branch.

Edit: Here are the functions and function definitions:
