string getTitle(){ return this->title; }

int getViewers(){ return this->viewers; }

vector<Show> shows;

vector<string> titles;

vector<int> viewers;

ifstream inFile1("file1.txt");

ifstream inFile2("file2.txt");

string line1, line2;

if(!inFile1.is_open() || !inFile2.is_open())

{

cout << "Either of the files could not be found!\n";

exit(0);

}

getline(inFile1, line1);

if(line1.compare("Show") == 0)

{

while(getline(inFile1, line1))

{

titles.push_back(line1);

}

inFile1.close();

}

getline(inFile2, line2);

if(line2.compare("Viewer") == 0)

while(getline(inFile2, line2))

{

viewers.push_back(stod(line2));

}

inFile2.close();

}

for(int i = 0; i < titles.size(); i++)

{

shows.push_back(Show(titles[i], viewers[i]));

gavmur [86]

Answer:

#include<iostream>

#include<fstream>

using namespace std;

int main()

{

ofstream out;

out.open("Hello.txt");

out << "Hello, World!"<< endl;

out.close();

ifstream in;

in.open("Hello.txt");

while(in.good()){

string line;

in >> line;

cout << line << endl;

}

in.close();

return 0;

}

Explanation:

Step 1:

Add all your preprocessor files directive, #include is known as the preprocessor is used to load files needed to run the code.

#include<iostream>: it provides basic input and output services for C++ programs.

#include<fstream>:used to open a file for writing and reading

using namespace std; means you'll be using namespace std means that you are going to use classes or functions (if any) from "std" namespace

Step 2:

ofstream out; his is used to create files and write data to the file

out.open("Hello.txt"); a new file "HELLO.txt" has been created

out << "Hello, World!"<< endl; "Hello World!" has now been writen to the file

out.close(); The file is now closed

This second step opens a new file and writes hello world to the file then closes it.

Step 3:

ifstream in; ifstream in c++ is a stream class which stands for input file stream a is used for reading data from file.

in.open("Hello.txt"); Reopens the file without recreating it. This is a very important step because if not done properly, you might discard the file you previously created and recreate it.

while(in.good()){

in.good() is true if the previous read operation succeeded without EOF being encountered

string line; It declares a string variable line

in >> line; reads the data into the line variable

cout << line << endl; Prints out the line

reopens the file and read the message into a string variable "line". prints out line then exits out of the file.

Jeffery wants to identify the subject terms being used in APA PsychInfo for articles related to behavior modifications. What is

schepotkina [342]

Group of answer choices.

a. He can look for common related subject terms in a dictionary, thesaurus or encyclopedia.

b. He can look for relevant articles in the results list from a database search and scan the subject terms.

c. He can use Go-ogle Scholar to retrieve relevant articles and find common related subject terms.

Answer:

b. He can look for relevant articles in the results list from a database search and scan the subject terms.

Explanation:

A Search engine is an internet resource or service that searches for keywords or categories specified by the end user and then displays (shows) a list of website which matches or have informations similar to the query. Some examples of popular search engines are Goo-gle, Bing, Yahoo, etc.

The most efficient and effective search strategy to identify subject terms for a database search is to look for relevant articles in the results list from a database search and scan the subject terms.

In order to improve the speed of retrieval for a search engine, high frequency words such as if, or, and, at, to, etc., which are generally referred to as stop words are filtered out.

However, AND should be used to combine keywords and phrases when using a "subject search" option to search a database for relevant articles.
