This is a menu$-$driven program that uses the following options:

a$)$ Add a new patient. The patient details $($name$,$ age, year of birth, ID$)$ are given as

function arguments. You should add the patient only if the patient is not already present

in the array $($compared by name, case sensitive$)$ and there is space in the array to add a

new patient.

b$)$ Display the all patients$$ information. See expected output below.

c$)$ Display only the patients whose age falls within a range $($in descending order$)$

d$)$ Display the oldest patient whose name starts with a specific character. Ask the user for

a character. This function is used to demonstrate garbage collection.
