Question

In statistics the mode of a set of values is the value that occurs most often. I need to write code that finds the mode of a user-specified array size. The code needs to be written inside the function arrayMode().

#include <iostream>
using namespace std;

int arrayMode(int *, int);

int main()
{
int *people;
int numppl;

cout << "How many people? ";
cin >> numppl;

people = new int[numppl];

cout << " Enter how many slices of pie each person eats in a year: " << endl;
for (int i = 0; i < numppl; i++)
{
cout << " Person " << (i + 1) << ": ";
cin >> people[i];
}

cout << " -----------------" << endl;
cout << " Mode: " << arrayMode(people, numppl) << endl << endl;
return 0;
}

int arrayMode(int *array, int size)
{
// Instead of code for the average, write code to find the mode of the array here.
int mode;
int total = 0;

for (int i = 0; i < size; i++)
total += array[i];
mode = total / size;

return mode;
}

Explanation / Answer

please rate - thanks

#include <iostream>
using namespace std;
int arrayMode(int *, int);

int main()
{
int *people;
int numppl;

cout << "How many people? ";
cin >> numppl;

people = new int[numppl];

cout << " Enter how many slices of pie each person eats in a year: " << endl;
for (int i = 0; i < numppl; i++)
{
cout << " Person " << (i + 1) << ": ";
cin >> people[i];
}

cout << " -----------------" << endl;
cout << " Mode: " << arrayMode(people, numppl) << endl << endl;
system("pause");
return 0;
}

int arrayMode(int *array, int size)
{
// Instead of code for the average, write code to find the mode of the array here.
int max=1,i=0,count=1,j,mode=0;
   j=-1;
   for(i=0;i<size-1;i++)
       {count=1;
        for(j=i+1;j<size;j++)
           {if(array[i]==array[j])
            count++;
            }
         if(count>max)
             {max=count;
             mode=i;
             }  
         }     
return array[mode];
}
