Hi,

I have created the program with just files, please see the output screenshots before executing the program.

Program:

//header files
#include <iostream>
#include<string>
#include <fstream>
#include <cstring>

using namespace std;

//function to display menu
char hospital_menu()
{
cout << "\nArkansas Children Hospital" << endl
<< endl;

cout << "a. Add new patient record" << endl;
cout << "b. search record" << endl;
cout << "c. Deletea record" << endl;
cout << "d. Print all records" << endl;
cout << "e. Exit " << endl;

char ch;
cout << "Enter your choice HERE=> ";
