Expected output

add:

Notice that since this is the first execution of the program, load() gave message Patient_List.txt not found. This file is created at the end of the program by save().

display: (after adding 3 patient details) CSE240

sort:

The 3 patients seen in display() output above are sorted in sort(). Use d option to verify sorted result.

load:

Notice the message given by load() Patients record loaded from Patient_List.txt at the top. To verify that load() worked as expected, use d display option to display loaded list.

// READ BEFORE YOU START: // You are given a partially completed program that creates a list of patients, like patients' record. // Each record has this information: patient's name, doctor's name, critical level of patient, room number. // The struct 'patientRecord' holds information of one patient. Critical level is enum type. // An array of structs called 'list' is made to hold the list of patients. // To begin, you should trace through the given code and understand how it works. // Please read the instructions above each required function and follow the directions carefully. // You should not modify any of the given code, the return types, or the parameters, you risk getting compile error. // You are not allowed to modify main (). // You can use string library functions.

// WRITE COMMENTS FOR IMPORANT STEPS IN YOUR CODE.
