/*
 *  C Program to sum odd integers in a matrix and return
 */

#include <stdio.h>
#include <assert.h>
#define NUM_ROWS 5

int f(int mat[][3], int num_rows)
{
  int i, j;
  int sum = 0;

  for (i = 0; i < num_rows; i++)
  {
    for (j = 0; j < 3; j++)
    {
      if (mat[i][j] % 2 != 0)
      {
        sum += mat[i][j];
      }
    }
  }

  return sum;
}

int main()
{
  int arr [NUM_ROWS][3] = { { -18, 5, 64 },
                            { -29, 77, -87 },
                            { 53, 14, 20 },
                            { 128, -64, -47 },
                            { 107, 87, -32 } } ;

  int sum = f(arr, NUM_ROWS);

  //munit_assert(sum == ((5) + (-29) + (77) + (-87) + (53) + (-47) + (107) + (87)));

  assert(sum == ((5) + (-29) + (77) + (-87) + (53) + (-47) + (107) + (87)));
