Answer:
Reliability feature in transport layer ensures correct order.
Explanation:
TCP (Transmission Control Protocol) is a communication protocol over network. TCP has a layered architecture and transport layer controls the data transmitted arrives in correct form. This is called reliability feature.
Control data header at transport layer ensures correct delivery. It tracks the transmitted data and re-transmits in case of en error.
Answer:
// here is code in java.
import java.util.*;
// class definition
class Main
{
// method that return the digits of number
public static void dig(int num)
{
// while loop
while(num>0)
{
// print the digits
System.out.println(num%10);
num=num/10;
}
}
//driver method
public static void main (String[] args) throws java.lang.Exception
{
try{
// scanner object to read input string
Scanner s=new Scanner(System.in);
// variable
int num;
System.out.print("please enter the number: ");
//read the number
num=s.nextInt();
// validate the input, read a positive number only
while(num<=0)
{
System.out.print("enter a positive number only:");
num=s.nextInt();
}
System.out.println("digit of number are:");
// call the function
dig(num);
}catch(Exception ex){
return;}
}
}
Explanation:
Read a number from user and assign it to variable "num".Check if it is positive or not.If input is negative then ask user to again enter a positive number till user enter a positive number.Then call the function with input number. In this method it will find the digits of the number in the while loop using modulus "%" operator.
Output:
please enter the number: -345
enter a positive number only:1234
digit of number are:
4
3
2
1
C??i think sorry if wrong ..
