Answer to Question #209927 in C++ for Maaz

Question

Suppose you are a programmer in Agha Khan Hospital. Agha Khan Hospital Chairman has assigned a task you

to develop an application in regards to handle the data related to COVID-19 Vaccination Registration. Each

patient is provided with a security code needed for verification at the time of vaccination. Range of security

code is 1 to 10.

Task is to create a class COVID with 6 private data members name, cnic, security code, age, address and blood

pressure of patient. Class include public member functions

1. input ( ) function to input the attributes of patient

2. verify ( ) function to check security code provided at the time of registration

3. display ( ) function to display the patient cnic if security code is verified

4. show ( ) function to display the message NOT REGISTERED if security code doesn’t match

Define verify function outside the class using scope resolution operator

Answer 1

#include <string>
#include <time.h>
