Answer:

Here is the C++ and Python programs:

C++ program:

#include<iostream>  //to use input output functions

using namespace std;  //to identify objects like cin cout

void swapvalues(int&  userVal1, int& userVal2); //function to swap values

int main() {  //start of main function

  int integer1,integer2;  //declare two integers

  cout<<"Enter first integer: ";  //prompts user to enter the first number

  cin>>integer1;  //reads first number from user

     cout<<"Enter second integer: "; //prompts user to enter the second number

  cin>>integer2;  //reads second number from user

 cout<<"Integers before swapping:\n";  //displays two numbers before swapping

 cout<<integer1<<endl<<integer2;  

  swapvalues(integer1, integer2);  //calls swapvalues method passing two integers to it

  cout << "\nIntegers after swapping:\n"; //displays two numbers after swapping

 cout<<integer1<<endl<<integer2; }

void swapvalues(int&  userVal1, int& userVal2){  //method that takes two int type numbers and swaps these numbers

  int temp;  //temporary variable

  temp = userVal1;  //temp holds the original value of userVal1

  userVal1 = userVal2;  //the value in userVal2 is assigned to userVal1

  userVal2 = temp; } //assigns value of temp(original value of userVal1) to userVal2

The program prompts the user to enter two integers and then calls swapvalues() method by passing the integers by reference. The swapvalues() method modifies the passed parameters by swapping them. The method uses a temp variable to hold the original value of first integer variable and then assigns the value of second integer variable to first. For example if userVal1 = 1 and userVal2 =2. Then these swapping statements work as follows:

temp = userVal1;  

temp = 1

userVal1 = userVal2;  

userVal1 = 2

userVal2 = temp;

userVal2 = 1

Now because of these statements the values of userVal1 and userVal2 are swapped as:

userVal1 = 2

userVal2 = 1

Explanation:

Python program:

def swap_values(user_val1, user_val2):  #method to swap two numbers

   return user_val2,user_val1   #returns the swapped numbers

integer1 = int(input('Enter first integer :')) #prompts user to enter first number

integer2 = int(input('Enter second integer :'))  #prompts user to enter second number

print("Numbers before swapping") #displays numbers before swapping

print(integer1,integer2)

print("Numbers after swapping") #displays numbers after swapping

integer1,integer2 = swap_values(integer1,integer2) #calls method passing integer1 and integer2 to swap their values

print(integer1,integer2) #displays the swapped numbers

The screenshot of programs and outputs is attached.

The program that swaps variables will return the reverse of the users input.  The second integer input will be printed first followed by the first integer input.

def swap_variables(first_input, second_input):

    return second_input, first_input

first_input = input("input the first integer: ")

second_input = input("input the second integer: ")

print(f"numbers before swapping are {first_input} and {second_input}")

print(f"numbers after swapping are {second_input} and {first_input}")

Answer:

ICMP echo requests.

Explanation:

A Domain Name System (DNS) can be defined as a naming database in which internet domain names (website URLs) are stored and translated into their respective internet protocol (IP) address. This simply means that, DNS is used to connect uniform resource locator (URL) or web address with their internet protocol (IP) address.

When troubleshooting Domain Name System (DNS) problems, one helpful feature the public servers usually support is an ICMP echo requests.

ICMP is an acronym for Internet Control Message Protocol and it is a standard protocol for communicating network errors in the form of messages such as Time exceeded and Destination unreachable.

In Computer Networking, an echo reply and echo request are implemented with a command utility referred to as ping. When a user sends an echo request message with the ping program, a successful attempt will return an echo reply message.

Hence, when troubleshooting Domain Name System (DNS) problems, a user should ping a public server such as a Google DNS server with the IP address (8.8.8.8 or 8.8.4.4), Cloudfare with 1.1.1.1 or the common 4.2.2.2 DNS server. If successful, it means the name-server was resolved properly into an IP address and therefore, there's an active connection on the network.

Based on the information given, the helpful feature that public servers usually support is the ICMP echo requests.

It should be noted that a Domain Name System simply means a naming database where the internet domain names are stored and translated into their respective internet protocol address.

It should be noted that when troubleshooting Domain Name System problems, the helpful feature that public servers usually support is the ICMP echo requests.

b) the Statement is Invalid

Explanation:

a)

lets Consider, s: student of my class

A(x): Getting an A

Let b: john

I have a student in my class who is getting ab A: Зs, A(s)

John need not be the student i.e b ≠ s could be true

Hence ¬A(b) could be true and the given statement is invalid

b)

Lets Consider G: girl scout

C: selling 50 boxes of cookies

P: getting prize

s: Suzy

Now every girl scout who sells at least 50 boxes of cookies will get a prize: ∀x ∈ G, C(x) -> P(x)

Suzy, a girl scout, got a prize: s ∈ G, P(s)

since P(s) is true, C(s) need not be true

Main Reason: false → true is also true

Therefore the Statement is Invalid

The argument that is valid is B. Every girl scout who sells at least 50 boxes of cookies will get a prize. Suzy, a girl scout, got a prize. Therefore Suzy sold 50 boxes of cookies.

It should be noted that a valid argument simply means the argument that's the conclusion can be derived from the premise given.

In this case, the argument that is valid is that every girl scout who sells at least 50 boxes of cookies will get a prize. Suzy, a girl scout, got a prize. Therefore Suzy sold 50 boxes of cookies.

for x in range(7):

   if (x == 3 or x==6):

       continue

   print(x, end=' ')

print("\n")

>> 0 1 2 4 5

The code above has been written in Python. The following explains each line of the code.

Line 1: for x in range(7):

The built-in function range(7)  generates integers between 0 and 7. 0 is included but not 7. i.e 0 - 6.

The for loop then iterates over the sequence of number being generated by the range() function. At each iteration, the value of x equals the number at that iteration. i.e

For the first iteration, x = 0

For the second iteration, x = 1

For the third iteration, x = 2 and so on up to x = 6 (since the last number, 7, is not included).

Line 2: if (x == 3 or x == 6):

This line checks for the value of x at each iteration. if the value of x is 3 or 6, then the next line, line 3 is executed.

Line 3: continue

The continue keyword is used to skip an iteration in a loop. In other words, when the continue statement is encountered in a loop, the loop skips to the next iteration without executing expressions that follow the continue statement in that iteration. In this case, the print(x, end=' ')  in line 4 will not be executed when x is 3 or 6. That means 3 and 6 will not be printed.

Line 4: print(x, end=' ')

This line prints the value of x at each iteration(loop) and then followed by a single space. i.e 0 1 2 ... will be printed. Bear in mind that 3 and 6 will not be printed though.

Line 5: print("\n")

This line will be printed after the loop has finished execution. This line prints a new line character.

The program is an illustration of loops.

Loops are used to perform repetitive operations.

The program in Python,  where comments are used to explain each line is as follows:

#This iterates from 0 to 6

for i in range(7):

   #This checks if the current number is not 3 or 6

   if not i==3 and not i == 6:

       #If yes, the current number is printed

       print(i,end=" ")

Explanation:

calculators work by processing information in binary form. We're used to thinking of numbers in our normal base-ten system, in which there are ten digits to work with: 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. The binary number system is a base-two system, which means there are only two digits to work with: 0 and 1. Thus, when you input numbers into a calculator, the integrated circuit converts those numbers to binary strings of 0s and 1s.

The integrated circuits then use those strings of 0s and 1s to turn transistors on and off with electricity to perform the desired calculations. Since there are only two options in a binary system (0 or 1), these can easily be represented by turning transistors on and off, since on and off easily represent the binary option

Once a calculation has been completed, the answer in binary form is then converted back to our normal base-ten system and displayed on the calculator's display screen.

Explanation:

The first phase, setting up an IPsec tunnel, is called IKE phase 1. There are two types of setting up an IPsec tunnel.

Phase 1 and Phase 2 of VPN discussions are separate stages. Phase 1's primary goal is to establish a safe, encrypted channel for Phase 2 negotiations between the two peers. When Phase 1 is successfully completed, the peers immediately begin Phase 2 negotiations.

When two dedicated routers are deployed in IPsec tunnel mode, each router serves as one end of a fictitious "tunnel" over a public network. In IPsec tunnel mode, in addition to the packet content, the original IP header containing the packet's final destination is also encrypted.

Therefore, the first phase, setting up an IPsec tunnel, is called IKE phase 1.

Explanation:

The program is well explained in the comments attached with each statement of the program. I will explain the program with the help of an examples. Suppose

integer1 = 7

integer2 = 15

integer3 = 3

first if condition  if (integer1 >= integer2 && integer1 >= integer3) checks if value of integer1 variable is greater than or equal to both integer2 and integers3 values. Since integer1 = 7 so it is greater than integer3 = 3 but less than integer2. So this statement evaluates to false because in && ( AND logical operator) both of the conditions i.e integer1 >= integer2 and integer1 >= integer3 should be true. So the program moves to the else if part.

The else if condition else if (integer2 >= integer1 && integer2 >= integer3) checks if value of integer2 variable is greater than or equal to both integer1 and integer3 values. Since integer2 = 15 so it is greater than integer1 = 7 and also greater than integer3 = 3. So this statement evaluates to true as both parts of the else if condition holds true. So the else if part executes which has the statement: cout<<integer2; which prints the value of integer2 i.e. 15 on output screen.

Output:

 }

 else if (num2 <= num1 && num2 <= num3)

 {

   printf("%i is the smallest number!\n", num2);

 }

 else

 {

   printf("%i is the smallest number!\n", num3);

 }

 return 0;

}

Explanation:

Alright so let's start with the requirements of the question:

So we needed to create 3 variables to hold each integer that was going to be passed into our script.

By using scanf("%i", &variableName) we were able to take in user input and  store it inside of num1, num2, and num3.

Since you mentioned you were new to the C programming language, I threw in the first if statement as an example of how they can be used, use it as a guide for future reference, sometimes it's better to understand your code visually.

Basically what this if statement does is, it checks to see if any of the integers that came in from user input was the number zero, it told the user it does not accept that number, please input a number greater than zero.

if (num1 == 0 || num2 == 0 || num3 == 0)

 {

   printf("please input a number greater than zero :)\n");

 }

I used this methodology and implemented the heart of the question,

whichever number is smaller, print it out on the shell (output).

if (num1 <= num2 && num1 <= num3)

^^ here we're checking if the first variable we created is smaller than the second variable and the third ^^

 {

   printf("%i is the smallest number!\n", num1);

   ^^ if it is smaller, then print integer and then print a new line so the next line looks neat ^^

   ( incase if your wondering what "\n" is, its a special character that allows you so print a new line on the terminal, kind of like hitting the return or enter key )

 }

else if (num2 <= num1 && num2 <= num3)

^^ else if is used when your checking for more than one thing, and so for the second variable we checked to see if it was smaller than the first and third variable we created ^^

 {

   printf("%i is the smallest number!\n", num2); < -- and we print if it's smaller

 }

Last but not least:

else

^^ if it isn't num1 or num2, then it must be num3 ^^

 {

   printf("%i is the smallest number!\n", num3);

  we checked the first two options, if its neither of those then we have only one variable left, and thats num3.

 }

I hope that helps !!

The reasons why a language would distinguish between uppercase and lowercase in its identifiers are:

(1) So that variable identifiers may look different than identifiers that are names for constants, such as the convention of using uppercase for constant names and using lowercase for variable names in C.

(2) So that the catenated words such as names can have their first letter distinguished, as in Total Words. The primary reason why a language would not distinguish between uppercase and lowercase in identifiers is it makes programs less readable, because words that look very similar are actually completely different, such as SUM and Sum.
