Question

Define a function called DisplayMax that has 3 parameters: the first two parameters are parallel arrays of different types and the third argument is of type size_t representing the size of both arrays. The function DisplayMax must work when called with various types of actual arguments, for example

string DisplayMax(string names[], int calories[], int size)

or

int DisplayMax(int calories[], float prices[], int size).

(Parallel Arrays are two arrays whose data is related by a common index. For example: with the string array and int array, index 3 of the string array would have some name, and index 3 of the int array would have an associated value to that name (say, number of calories).)

Write one function that will take either set of arguments in, displays and return the value from the first second array corresponding to the max value from the second first array, in the form “The max value of <int/float value> belongs to <string/int value>.”

Test your function by calling it with different inputs from a main() function and then printing the result of the function in the main program.

Examples:

Given:

names => string[] = {“Yogurt Lemon”, “Chocolate Delight”, “Choco Chip”, “Frozen Sorbet”, “Melon”}

calories => int[] = {300, 650, 550, 450, 50}

size => int = 5

Output:

“The max value of 650 belongs to Chocolate Delight.”

Given:

calories => int[] = {300, 35, 650, 550, 450, 50}

prices => float[] = {2.99, .99, 2.79, 3.19, 1.79, 2.15}

size => int = 6

Output:

“The max value of 650 belongs to 2.79.”

#include <iostream>
using namespace std;

string DisplayMax(string names[], int calories[], int size)
{
   int max = calories[0];
   int index = 0;
  
   for(int i=1;i<5;i++)
   {
       if(calories[i] > max)
       {
           max = calories[i];
           index = i;
       }
   }
   cout<<"The max value of "<<max<<" belongs to ";
   return names[index];
  
}
int DisplayMax(int calories[], float prices[], int size)
{
   int max = prices[0];
   int index = 0;
  
   for(int i=1;i<5;i++)
   {
       if(calories[i] > max)
       {
           max = calories[i];
           index = i;
       }
   }
   cout<<"\nThe max value of "<<max<<" belongs to ";
   return index;
}
int main() {
  
   string names[] = {"Yogurt Lemon", "Chocolate Delight", "Choco Chip", "Frozen Sorbet", "Melon"};
   int calories[] = {300, 650, 550, 450, 50};
   float prices [] = {2.99, .99, 2.79, 3.19, 1.79, 2.15};
   int size = 5;

string str;
str = DisplayMax(names,calories,size);
cout<<str<<".";

int index;
index = DisplayMax(calories,prices,size);
cout<<prices[index]<<".";
   return 0;
}

Output:

The max value of 650 belongs to Chocolate Delight.
The max value of 650 belongs to 0.99.
