Answer:

Verbatim Identifier

Explanation:

  • Verbatim Identifier contains @ symbol as a prefix by which enables you to use reserved words of a programming language as identifier. For example the keywords like int, double, goto, char, else, while, for, float etc can be used as strings or variable names if @ symbol is added before these words e.g. @char, @while, @void, @int etc.
  • The compiler of a language will recognize such identifiers as verbatim identifiers and compiles them without giving an error that these are reserved words.
  • Verbatim identifier is used for program that is written in other languages and those languages don't have same reserved words.
  • For example: cout<<"use of verbatim identifier";<<@for;   In this statement, for keyword which is used in for loop can be used as an identifier with @ in the prefix.
  • The escape sequences if used with @ symbol in prefix then they are interpreted in a different way. For example in C#

                              string a = "\\C:\torrent\new\file";

                              Console.WriteLine(a);

This statement will give the following output:

                              \C:          orrent

                               ewfile

This means that the \t in the start of torrent and \n in the start of new word is taken as an escape sequence and output displayed is giving tab space because of \t and prints the rest of the words in new line because of \n escape sequence.

Now lets use this with the @ symbol

                               string a = @"\\C:\torrent\new\file";

                                Console.WriteLine(a);

The output will now be:

                                \\C:\torrent\new\file

\t and \n are not taken as escape sequences by the compiler because of @ symbol.

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.
