Question

what am i doing wrong here ? starting out with c++ early objects 9th edition chapter 10 programming challenge 6

#include <iostream>
using namespace std;

int main() {
  
   double findMedian(int* numbers, int size) {
   double median;
   if (size % 2 == 0)
       median = (double)(*(numbers + ((size - 1) / 2))
           + *(numbers + (((size - 1))) / 2;
   else
               median = *(numbers + ((size - 1) / 2));
   return median;
}

double findMedian(int*, int);
const int SIZE = 5;
   int numbers[SIZE] = { 2, 4, 5, 7, 8 };
   std::cout << "Median of array is:" << median;
   return 0;
}

double findMedian(int* numbers, int size) {

   double median;
   if (size % 2 == 0);
   median = (double)(*(numbers + ((size - 1) / 2)) + *(numbers + (((size - 1) / 2) + 1))) / 2;
   else
       median = *(numbers + ((size - 1) / 2));
   return median;
}

#include <iostream>

using namespace std;

double findMedian(int *, int);

int main() {
    const int SIZE = 5;
    int numbers[SIZE] = {2, 4, 5, 7, 8};
    std::cout << "Median of array is:" << findMedian(numbers, SIZE) << endl;
    return 0;
}

double findMedian(int *numbers, int size) {
    double median;
    if (size % 2 == 0)
        median = (double) (*(numbers + ((size - 1) / 2)) + *(numbers + (((size - 1) / 2) + 1))) / 2;
    else
        median = *(numbers + ((size - 1) / 2));
    return median;
