Answer:
//C++ code for the cash register..
#include <iostream>
#include<vector> //including vector library
using namespace std;
int main() {
vector<float> cash; //declaring a vector of type float.
float item=2,cash_sum=0;
int counter=1;
while(item!=0)//inserting prices in the vector until user enters 0...
{
cout<<"Enter the price of item "<<counter<<" :"<<endl;
cin>>item;
counter++;
cash.push_back(item);//inserting element in the vector...
}
for(int i=0;i<cash.size();i++)//looping over the vector...
{
cash_sum+=cash[i];//summing each element..
}
cash_sum*=1.08;//adding 8% sales tax.
cout<<cash_sum;//printing the result....
return 0;
}
Explanation:
I have taken a vector of type float.
Inserting the price of each item in the vector until user enters 0.
Iterating over the vector for performing the sum operation.
Then after that adding 8% sales tax to the sum.
Printing the output at last.
I think the answer is true because casting has been found 6000 years ago!
Answer:
Network Address Translation (NAT)
Explanation:
With the aid of Network address translation(NAT), the IP addresses of a particular local network are translated or mapped into a single or multiple global or public IP addresses. Therefore, a wireless router could use NAT to translate its private IP address on internal traffic (network) to a routable address for the internet.
With NAT, businesses can use many internal IP addresses since they are just for internal purposes and will be eventually converted into a single or a few multiple routable IP addresses.
Three types of NAT are possible:
(i) Static NAT : There is a one - to - one mapping between private IP addresses and routable (public) IP addresses. One private IP is mapped to one public IP address.
(ii) Dynamic NAT : There is a many- to - many mapping between private IP addresses and routable (public) IP addresses. Multiple private IPs are mapped to many public IP addresses.
(iii) Port Address Translation (PAT) : Many - to - one relationship between the private IP addresses and public addresses. Many private IP addresses can be mapped or translated into a single public IP address. This type of NAT is also called NAT overload.
