The code can be found attached.

So let's write a code that will be a recognition function, like this:

def owl_count(text):"I really like owls. Did you know that an owls eyes are more than twice as big as the eyes of other birds of comparable weight?"

word = "owl"

texts = text.lower()

owlist = list(texts.split())

count = text.count(word)

num = [owlist, count] #num has no meaning just random var

print(num)

Answer:

lookup value   =  "paramount"

Search table   =  A1:A4

Result table     =  B1;B4

Explanation:

lookup, what are we looking up.....:::///????Paramount

What is the beginning search table......A1;A4

Column B contains the words meanings.....this is the result we want:

So the Result table......B1:B4

LOOKUP("paramount"; B1:B4; A1:A4)  should Pat write the LOOKUP function.

Lookup functions entail accessing a cell, comparing its values to those in an adjacent row or column, and then extracting the relevant answers from the associated columns or rows of Excel.

The lookup value, the search table, and indeed the result table are the three inputs required by the LOOKUP function. The value you are searching for, in this case, "paramount," is the lookup value.

The table that contains the lookup value, throughout this example B1:B4, is known as the search table.

The table where the results of the lookup are stored is known as the result table, and in this example, A1:

Pat should use the columns which would have the cell value of B1, B4 as well as A1.

A compiler translates a program written in a high level language

A compiler translate the entire program source code at once to produce object code, so a program written in low-level language runs faster than an equivalent program written in high-level language.

A compiler can be defined as a software program that is designed and developed to translate the entire source code of program at once, so as to produce object code, especially a software program that is written in a high-level language into low-level language (machine language).

In conclusion, we can deduce that a compiler translate the entire program source code at once to produce object code, so a program written in low-level language runs faster than an equivalent program written in high-level language.

#include<iostream>

using namespace std;

class Money{

    private:

        int dollars;  

       int cents;

   public:

       Money(int d=0, int c=0){

          setDollar(d);

          setCent(c);

       }

       void setDollar(int d){

           dollars = d;

       }

       void setCent(int c){

           cents = c

       }

       int getDollar() {

           return dollars;

       }

       int getCent() {

           return cents;

       }

       double getMoney(){

          return (dollars + (cents/100));

       }

};

// testing the program.

int main(){

  Money Acc1(3,50);

  cout << M.getMoney() << endl;

  Money Acc2;

  Acc2.setDollars(20);

  Acc2.setCents(30);

  cout <<"$" << Acc2.getDollars() << "." << Acc2.getCents() << endl;

  return 0;

}

Explanation:

The C++ source code defines the Money class and its methods, the class is used in the main function as a test to create the instances of the money class Acc1 and Acc2.

The object Acc2 is mutated and displayed with the "setDollar and setCent" and "getDollar and getCent" methods respectively.

using namespace std;

int main(){

   int hour; char pkg; float bill = 0;

   cout<<"Package: "; cin>>pkg;

   cout<<"Hour: "; cin>>hour;

   if(hour<=744 && hour >=0){

       switch (pkg) {

           case 'A':

               bill = hour * 9.95;

               if(hour >10){bill = 10 * 9.95 + (hour - 10) * 2;}

           break;

           case 'B':

               bill = hour * 14.5;

               if(hour >10){bill = 20 * 14.5 + (hour - 20) * 1;}

           break;

           case 'C':

               bill = 19.95;

           break;

           default:

               cout << "Package must be A, B or C";}

cout<<"Total Bills: $"<<bill; }

else{ cout<<"Hour must be 0 - 744"; }

return 0;

}

Explanation:

This declares all variables:    int hour; char pkg; float bill=0;

This prompts the user for package type:  cout<<"Package: "; cin>>pkg;

This prompts the user for number of hours:    cout<<"Hour: "; cin>>hour;

This checks if hour is between 0 and 744 (inclusive)

   if(hour<=744 && hour >=0){

If true, the following is executed

A switch statement to check valid input for package

       switch (pkg) {

For 'A' package

           case 'A':

Calculate the bill

               bill = hour * 9.95;

               if(hour >10){bill = 10 * 9.95 + (hour - 10) * 2;}

End of A package:            break;

For 'B' package

           case 'B':

Calculate the bill

               bill = hour * 14.5;

               if(hour >10){bill = 20 * 14.5 + (hour - 20) * 1;}

End of B package:            break;

For C package            

           case 'C':

Calculate bill:                bill = 19.95;

End of C package:            break;

If package is not A, or B or C

           default:

Prompt the user for valid package                cout << "Package must be A, B or C";}

Print total bills: cout<<"Total Bills: $"<<bill; }

If hour is not 0 to 744: else{ cout<<"Hour must be 0 - 744"; }

Online, it is easy to think of communication as “computer to computer” rather than “person to person”. Thus, option D is correct.

It is possible to describe communication as the act of passing the information between one person or group of people to the next. Communicating facilitates easy understanding of what a different person is trying to say or convey. There are two forms of communication: both verbal and nonverbal.

With the help of communication the person can tell and feature tthe data between the person and an group. In this, that data is given to the people and the data is not given to the person but it is rather given to the person. As this data is been transferred from one computer to another and then it reaches the people.

Therefore, option D is the correct option.

Explanation:

This line defines the function

def  meters_to_laps(length):

#include<iostream>

#include<vector>

using namespace std;

int main(){

   int len, num;

   vector<int> vect;

   cout<<"Length: ";

   cin>>len;  

   for(int i = 0; i<len;i++){

       cin>>num;

   vect.push_back(num);}

   vector<int>::iterator iter;

   for (iter = vect.end() - 1; iter >= vect.begin(); iter--){

       cout << *iter << ", ";}    

}

Explanation:

This declares the length of vector and input number as integer

   int len, num;

This declares an integer vector

   vector<int> vect;

This prompts the user for length  

cout<<"Length: ";

This gets the input for length  

   cin>>len;  

The following iteration gets input into the vector

   for(int i = 0; i<len;i++){

       cin>>num;

   vect.push_back(num);}

This declares an iterator for the vector

   vector<int>::iterator iter;

The following iterates from the end to the beginning and prints the vector in reverse

   for (iter = vect.end() - 1; iter >= vect.begin(); iter--){

       cout << *iter << ", ";}

Brief History Of Computer. The computer as we know it today had its beginning with a 19th century English mathematics professor name Charles Babbage. ... Other developments continued until in 1946 the first general– purpose digital computer, the Electronic Numerical Integrator and Computer (ENIAC) was built.

Explanation:

Computers and electronics play an enormous role in today's society, impacting everything from communication and medicine to science.

Although computers are typically viewed as a modern invention involving electronics, computing predates the use of electrical devices. The ancient abacus was perhaps the first digital computing device. Analog computing dates back several millennia as primitive computing devices were used as early as the ancient Greeks and Romans, the most known complex of which being the Antikythera mechanism. Later devices such as the castle clock (1206), slide rule (c. 1624) and Babbage's Difference Engine (1822) are other examples of early mechanical analog computers.

The introduction of electric power in the 19th century led to the rise of electrical and hybrid electro-mechanical devices to carry out both digital (Hollerith punch-card machine) and analog (Bush’s differential analyzer) calculation. Telephone switching came to be based on this technology, which led to the development of machines that we would recognize as early computers.

The presentation of the Edison Effect in 1885 provided the theoretical background for electronic devices. Originally in the form of vacuum tubes, electronic components were rapidly integrated into electric devices, revolutionizing radio and later television. It was in computers however, where the full impact of electronics was felt. Analog computers used to calculate ballistics were crucial to the outcome of World War II, and the Colossus and the ENIAC, the two earliest electronic digital computers, were developed during the war.

With the invention of solid-state electronics, the transistor and ultimately the integrated circuit, computers would become much smaller and eventually affordable for the average consumer. Today “computers” are present in nearly every aspect of everyday life, from watches to automobiles.

The history of computers is one that began far back 2000 years ago in the city of Babylonia where there was the use of  abacus and it has grown to now the use of digital computer as it start in 1642. ​

The history of computers is one that is more than 200 years but in the 19th century, there was the invention of  mechanical calculating machines.

Note that the The 1st generation of computers was said to have existed from the year 1940 to 1955 and now it has grown to a whole new level.
