Having trouble with adding/sorting/searching to an array of a class.

[groundskeeperwillie]

Hi, I am having some trouble with this project that requires me to display a menu and then allow the user to select if they would like to add to the patient list, print the list, sort by last name, sort by ID, and search by last name and ID.

Since this array is of class patientType I am having some trouble bubble sorting and binary searching. I created a function to return the patients last name and ID, and now I need to be able to search by ID and last name, as well as sort by ID and last name.

Unfortunately my code isn't compiling (I'm getting a bunch of overloaded-function errors which I am not familiar with.)

How can I fix these overload errors to at least get my code to compile?

I realize there are also many issues with my select item function, as i cant figure out how to make it run as a switch function and not in my main code.

How can I run these functions in a switch?

I know this is a lot of code...if anyone helps it would be absolutely appreciated.

The answer is pretty simple:

This is your function decleration:
int addPatient(patientType patients[], int& length);
That's how you call the function:
addPatient();

When calling a function you need to provide the parameters.
