Answer:
#include <iostream>
using namespace std;
int main() {
   int k;
double d;
string s;
cin >> k >> d >> s;
cout << s << " " << d << " " << k << "\n" << k << " " << d << " " << s; }
                                                                    
Explanation:
k is int type variable that stores integer values.
d is double type variable that stores real number.
s is string type variable that stores word.
cin statement is used to take input from user. cin takes an integer, a real number and a word from user. The user first enters an integer value, then a real number and then a small word as input. 
cout statement is used to display the output on the screen. cout displays the value of k, d and s which entered by user. 
First the values of k, d and s are displayed in reverse order. This means the word is displayed first, then the real number and then the integer separated again by EXACTLY one space from each other. " " used to represent a single space.
Then next line \n is used to produce a new line. 
So in the next line values of k, d and s are displayed in original order (the integer , the real, and the word), separated again by EXACTLY one space from each other.
The program along with the output is attached.

Answer:
The "service password-encryption" global configuration command encrypts passwords configured before and after the command is issued.
Explanation:
A switch is an intermediate network device that is used to transfer frames to nodes on its collision domain. It operates in the Data-link layer of the OSI model.
Switches uses media address control (MAC) table, containing the MAC addresses of the nodes in the network, to determine the destination of nodes.
In the global configuration mode in a switch, the password and other protocols are configured. The service password-encryption command in the global execution mode encrypts passwords configured before and after the command.
