Thread: finding mode/multiple occurrence in array

im not sure how to go about in doing. ive tried implementing some techniques ive seen but to no luck , they havent worked. Can anyone guide me to the right direction?

Code:

#include <iostream> 
#include <iomanip>
using namespace std;
int main()
{
   cout << fixed << setprecision(1);
   float userMin;
   float userMax;
   const int SIZE = 21;
   float arr[SIZE];
   const int SIZE2 = 21;
   float arr2[SIZE2];
   int count = 0;
   cout << "enter min ";
   cin >> userMin;
   cout << "enter max ";
   cin >> userMax;
   float inc = (userMax - userMin) / (SIZE-1);
   float x = inc*count + userMin;
   for (; x <= userMax;)
   {
      for (int e = 0; e < SIZE; e++)
      {
         arr[e] = x;
         arr2[e] = (0.0572*cos(4.667*x) + 0.0218*cos(12.22*x));
         cout << setw(15) << setprecision(1)<< arr[e]
            << setw(15) << setprecision(3) << arr2[e]
            << endl;
         count++;
         x = userMin + inc*count;
      }
   }
   int teco = 1;
   int mode1 = 1;
   int ltnum = arr2[0];
   for (int index = 1; index < SIZE; index++)
   {
      if (ltnum == arr2[index])
      {
         ++teco;
      }
      else
      {
         ltnum = arr2[index];
         if (teco > mode1)
         {
            mode1 = teco;
         }
         teco = 0;
      }
   }
       
   return 0;
}
