Answer:
1. There are many ways to write an algorithm. Some are very informal, some are quite formal and mathematical in nature, and some are quite graphical. The instructions for connecting a DVD player to a television are an algorithm. A mathematical formula such as πR2 is a special case of an algorithm. The form is not particularly important as long as it provides a good way to describe and check the logic of the plan. The development of an algorithm, a plan is a key step in solving a problem. Once we have an algorithm, we can translate it into a computer program in some programming language. Our algorithm development process consists of five major steps.
2. computers only do what you told them to do, so If you wrote something wrong or you wasn't precise enough it might cause a massive damage and cause you to lose a lot of money.
3. You know when a problem should be solved whenever you need to make a decision that is important, or requires human intelligence and a computer doesn’t have human intelligence.
4. The process does sound familiar to me; it is like the mechanism of operation of the computer. Through reflex actions, our bodies take in input and respond sometimes without our control, such as shivering, blinking, and sneezing.
5. The brain uses chemicals to transmit information; the computer uses electricity. Even though electrical signals travel at high speeds in the nervous system, they travel even faster through the wires in a computer. Both transmit information. A computer uses switches that are either on or off ("binary").
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.
Answer:
Demilitarized zone (DMZ).
Explanation:
Demilitarized zone is a kind of security assurance scheme used by network administrator to detect network breach even before it gets to the secured network.
The private LAN is protected with a firewall and a DMZ is configured to allow access by untrusted users, on another workstation, which is a duplicate of the companies private local address.
There are 6 octects ( 8 bit numbers ) in a MAC address, so there's 256^6 possible addresses.
