Answer:
# include <iostream.h>
# include <stdio.h>
# include <string.h>
using namespace std;
class citizen
{
int i;
public string name[30];
public long int phonenumber[30];
public void addindividual(string name1)
{
If (i<=30)
{ int flag=0;
for(int j=0; j<=i;j++)
{
if (strcmp(name[i], name1)
{
flag=1;
}
else
{
flag=0;
}
}
If (flag)
{
if (i<30)
{
for(j=i+1;j<=30; j++)
{
cout<<"Enter the name:"; getchar(name[j]);
cout<<"Enter the phone number:"; cin>>phonenumber[j];
i++;
}
else
{
cout<<"The person already exists";
exit();
}
}
else
{
cout<<"array is full:";
exit();
}
}
}
Void main()
{
string str;
cout<<" Enter name:";
getline(cin, str); ;
citizen c1=new citizen();
c1.addindividual(name1);
}
Explanation:
With a little more effort you can make the program allow the user to enter any number of details, but less than 30 overall. We have used here flag, and as a programmer we know why we use the Flag. It is used to check whether certain Boolean condition is fulfilled or not. Here, we are checking whether a given name is present in the array of names, and if it is not present, we add that to the list. And if the name is present, we print, it already exist.
Correct answer would be <span>A) <u>quartz</u></span>. Plastic, nylon, and rubber can all be broken down or heated to make it expand, and be used in common products.

Example:
- Magnetic storage device:hard drive,floppy diskette etc.
- optical: Blu-ray disc,CD Rom disc.
Flash memory device:memory card memory sick,ssd
Hardware:
Hardware include the physical features,which are every part that you can either see or touch, for example monitor,case,keyboard,mouse and printer.
Software:
The part which activate the physical components called software. it includes the features that resposible for directing the work to the hardware.
