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 fi ndMost Subs to determine which publication has the most subscribers. Function findMbst 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 1/ corresponding publications int nr Most Subscriptions; // nunber of subscriptions for // publication wth nost subscriptions string nost Subscriptions; il title of publication with nost // 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, nost Subscriptions, nr Most Subscriptions); [TURN OVER] 10 COS1511 MAY/JUNE2020 Write down ONLY the complete function find Most Subs.

Answer 1

The required function is

void findMostSubs(string publications[],int subscriptions[], string * mostSubscriptions, int * nrMostSubscriptions)
{
  
   int max_index; //index of max subscription array

   int max = subscriptions[0]; // Initialize maximum element
   for (int i = 1; i <NUM_PUBS; i++)
   {
   // Traverse array elements from second and compare every element with current max
   if (subscriptions[i] > max)
       {
       max = subscriptions[i];
           max_index=i;
       }
   }
   *nrMostSubscriptions=subscriptions[max_index];
   *mostSubscriptions=publications[max_index];
}
