Our favorite program runs in 10 seconds on computer A, which has a 2 GHz clock. We are trying to help a computer designer build a computer, B, which will run this program in 6 seconds. The designer has determined that a substantial increase in the clock rate is possible, but this increase will affect the rest of the CPU design, causing computer B to require 1.2 times as many clock cycles as computer A for this program. What clock rate should we tell the designer to target?

Phishing Scam

• Change all the credentials on the site that you have disclosed.
• Immediately report the mail to an IT department and necessary authorities.
• Mark the mail as span and block the mail id.

Suspicious File Attachment

• May be that the suspicious file contains a virus file. Often such viruses are attached to external "Show-case" files so that the victim is not able to identify them. Once the external file is tried to open, the virus slips into the main memory (your RAM) and start executing in the background, creating copies of itself and executing every copy. Soon they start eating up the main memory (The memory that runs all your programs) making your PC slow to respond.

Antivirus Software Outdated

• Connected to the Internet and update the antivirus.

Laptop's Physical Security

• Set a password.
• install a tracking software.

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.

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'))

Answer:

The correct answer for the given question is option(a) i.e Local - within that function.

Explanation:

The variable which is declared inside any function are called as local variable The scope and lifetime of local variable is inside that block or function only.

They cannot access outside the function.

Following are the example of local variable

#include <stdio.h> // header file

void fun(); // function prototype

int main()// main function

{

fun(); //calling function

print("%d",t); // it gives error because t is local variable cannot access in main function

return 0;

}

void fun()

{

int t=9;// local variable

printf("t is local variable which value is:");

printf("%d",t);

}

As we seen that t cannot access outside the function .So correct answer is option(a)

Final answer:

The scope of a variable declared inside of a function is local - within that function. This prevents naming conflicts and ensures control over where a variable can be changed.

Explanation:

The scope of a variable declared inside of a function is typically local to that function. This means that it can only be accessed and manipulated within the function it is declared. It is not visible or accessible from outside of the function or elsewhere in the program file, hence options b) and c) are incorrect. This principle is fundamental in programming languages such as JavaScript, C++, Python, etc., and it is designed this way to prevent naming conflicts and provide control over where a variable can be changed.

Deque: You need to keep a record of the ages of the last 50 customers visit a restaurant. As new customers come in you delete the age that has been in the list the longest.

Tuple: You need to store the GPS coordinates of the hospitals in a state in order to find the nearest hospital for ambulance helicopters.

List: You write a loop to save anywhere from 10 to 100 values from a user. You will pass the collection to a function to find the average.

The icd-10-cm includes codes with three characters as the header of a group of codes that may be further split by the use of four, five, or six characters; this is known as the level of detailing in coding.

What does coding actually mean?

Describe coding. Coding, often known as computer programming, is how we communicate with computers. Because coding gives instructions to a machine, it is comparable to writing a set of rules. By learning to write code, you can tell machines much more quickly what to do or how to act.

What three forms of coding are there?

Languages written in an imperative, functional, logical, or object-oriented style are common. These coding language paradigms are available for programmers to select from in order to best meet their demands for a given project.
