Explanation: I just did the assignment and got it right
Answer:
import java.util.Scanner;
public class CalculatingSales {
public static void main(String[] args) {
Scanner sc = new Scanner(System.in);
int product, quantity;
double total = 0;
while(true) {
System.out.println("Enter product_id and quantity(0 0 to stop): ");
product = sc.nextInt();
quantity = sc.nextInt();
if(product==0 && quantity == 0)
break;
switch (product) {
case 1:
total = total + 2.98*quantity;
break;
case 2:
total = total + 4.50*quantity;
break;
case 3:
total = total + 9.98*quantity;
break;
case 4:
total = total + 4.49*quantity;
break;
case 5:
total = total + 6.87*quantity;
break;
default:
System.out.println("Invalid option");
}
}
System.out.println("total value: "+total);
sc.close();
}
}
Explanation:
- Take the product and quantity as input from user.
- Use a switch statement to multiply the total with their relevant value.
- Display the total value.
Answer:
"message encoding, message size and message delivery" are the correct answer for the above question.
Explanation:
The above defined are the three requirements which are defined as the protocol used in communication. These three requirements are a very essential part of communication because-
- Message Encoding is the first requirement, which is used to encode the message so that the hacker can not hack the communication data from the network.
- The second requirement is Message size which fixed the size and the number of packets used to send for the communication.
- The third requirements are Message delivery, for which the protocol needs to define the mechanism to overcome the loss of the data.
