● simple way to solve this is to sort array in ascending order & then taking out values at index n-2 & 1.

You should first get the largest and the smallest numbers in the array, then go through the array and check every number that is greater then previous number and smaller then largest number.
For the second smalles do same thing but check for every number that is smaller then previous and greater then smallest number!
for example:
int arr[6] = {1, 2, 3, 4, 5, 6};
int secondMax = 0;
int secondMin = 0;

for(int i = 0; i < 6; i++)
{
if( arr[i] > secondMax && i < 6)
secondMax = arr[i];
}

for(int i = 0; i < 6; i++)
{
if(arr[i] < secondMin && i > 1)
secondMin = arr[i];
}
