Answer:

see explaination

Explanation:

import re

def emails(document):

"""

function to find email in given doc using regex

:param document:

:return: set of emails

"""

# regex for matching emails

pattern = r'[\w\.-]+at[\w\.-]+\.\w+'

# finding all emails

emails_in_doc = re.findall(pattern, document)

# returning set of emails

return set(emails_in_doc)

# Testing the above function

print(emails('random text ertatxyz.com yu\npopatxyz.com random another'))

Correct Answer: citizens

Answer:a)Stand-alone

Explanation: Stand-alone application is the application that is found on the system of every client.In accordance with the IT section, Business intelligence can be transferred into stand-alone application .This helps in the development of the essence of the system at an independent level.

Other options are incorrect because supporting a certain factor will not make it independent, cannot act as the group of ISs technology or web system for gaining profit.Thus,the correct option is option(a).

Answer:

Following are the program in the C++ Programming Language.

//header file

#include<iostream>

//header file

#include <bits/stdc++.h>

//namespace

using namespace std;

//set main function

int main()

{

//set float type variables

float a,s,m,d,c,b,g;

//print message and get variable from the user

cout<<" Enter The First Number : ";

cin>>c;

//print message and get variable from the user

cout<<" Enter The Second Number: ";

cin>>b;

again:

//get variable from the user for Operation

cout<<" Enter the Operation which you want : ";

char choice;

cin>>choice;

//Addition

a=c+b;

//Subtraction

s=c-b;

//Multiplication

m=c*b;

//Division

d=c/b;

//Modulus

g=fmod(c, b);

//set switch statement

//here is the solution

 switch(choice)

 {

   case '+':  

     cout<<"Addition: "<<a<<endl;

     goto again;

     break;

   case '-':

     cout<<"Subtraction: "<<s<<endl;

     goto again;

     break;

   case '*':

     cout<<"Multiplication: "<<m<<endl;

     goto again;

     break;

   case '/':

     cout<<"Division: "<<d<<endl;

     goto again;

     break;

   case '%':

     cout<<"Modulus: "<<g<<endl;

     goto again;

     break;

   default:

     cout<<"Exit";

     break;

 }

return 0;

}Explanation:

Here, we define the required header files then, we set main function.

• set float type variables a,s,m,d,c,b,g.
• Get input from the user for operation in the variable c,d.
• Set character type variables in which we get input from the user for operations.
• Then, we perform some operations.
• Set switch statement which display the output according to the user an if user input wrong then statement breaks.
