Question

QUESTION 3 13 marks In this question you have to write a complete function. MyMedia Publishers uses two parallel arrays to keep track of the number of subscriptions for each of their 50 publications. Array publications holds the names of the magazines and newspapers published and array subscriptions holds the number of subscriptions for each corresponding magazine or newspaper. You have to write a void function, called findMost Subs to determine which publication has the most subscribers. Function findMost Subs has to return the name of the publication as well as the number of subscribers to that publication. Assume the following: a declaration of a global constant: const int NUM PUBS - 50: //number of publications four declaration statements in the main function: string publications [NUM PUBS); // titles of the publications int subscriptions [NUM PUBS); // number of subscriptions for the // corresponding publications int nrMost Subscriptions // number of subscriptions for // publication with most subscriptions string most subscriptions; // title of publication with most // subscriptions values have been assigned already to all the elements of the arrays the function is called in the main program as follows: findMost Subs (publications, subscriptions, most subscriptions, ni Most Subscriptions); [TURN OVER

Answer 1

Program:

please find the below program to find the maximum subscriptions for a journal and number of subscribers.

#include <iostream>

using namespace std;
//declaring constant variable
const int NUM_PUBS = 50;
//declaring the findMostSubs function
void findMostSubs(string publications[], int subscriptions[], int nMostSubscriptions, string mostSubscriptions);

//defining the findMostSubs function
void findMostSubs(string publications[], int subscriptions[], int nMostSubscriptions, string mostSubscriptions)
{
//declaring an integer variable to store the maximum subscriptions in the array
int index = 0;
//for loop to find the max element in an array - subscriptions
for(int i =0;i<NUM_PUBS;i++)
{
if(subscriptions[i] > nMostSubscriptions) {
nMostSubscriptions = subscriptions[i];
index = i;
}
}
//given 2 arrays are parallel,
//hence we can use the index of Subscriptions array to fetch the title name from publications array
mostSubscriptions = publications[index];
cout << "The name of the publication that has most subscriptions is " << mostSubscriptions << endl;
cout << "The number of subscribers to " << mostSubscriptions << " are " << nMostSubscriptions;

}

int main()
{
//declaration of an array to store titles of the publications.
//here i'm initializing the arrays statically
string publications[NUM_PUBS] = {"Newyork Times","HelloAPP","TimesNow","The Hindu", "missouri", "LondonTimes",
"USA Today","The Wall Street Journal","New York Post","Los Angeles Times", "The Washington Post",
"Star Tribune", "Newsday", "Chicago Tribune", " The Boston Globe", "Alaska", "Bloomsberg",
"India Today", "Inshorts", "Quora", "Mediumdigest", "ABC", "Stockexchange", "UK Today", "Alabama",
"Economic Times","Arizona", "phoenix", "california", "colorado", "Georgia","florida", "Hawaii", "Indiana",
"Mississippi", "New Jersey", "Newyork", "New Mexico","Financial Times","The Daily Telegraph","The Times",
"The Sunday Times", " The Guardian", "IEE journal", "Nature", "Finance Management", "Nature Nano technology",
"Environmental research","Journal of Cancer","Journal of Biosciences"};
//declaration of an array to store titles of the subscriptions.
int subscriptions[NUM_PUBS] = {3,20,20,40,60,1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 3, 12, 4,12,
46, 90, 10,23, 3, 345,4, 17, 50,21,23,31,32,24,25,65,43,27,87,67,90,0,2,43,54,65,76,87,98,79};

//declaring a integer variable to store number of subscriptions for publication with most subscriptions
//initializing the number of subscriptions as 0
int nMostSubscriptions=0;
//declaring a string varibale to store title of publication with most subscriptions
//initializing the mostSubscriptions as empty string.
string mostSubscriptions="";
  
//calling findMostSubs function
findMostSubs(publications, subscriptions, nMostSubscriptions, mostSubscriptions);

return 0;
}

Output:

The name of the publication that has most subscriptions is Economic Times The number of subscribers to Economic Times are 345 ... Program finished with exit code 0 Press ENTER to exit console.
