Write a function getNeighbors which will accept an integer array, size of the array and an index as parameters. This function will return a new array of size 2 which stores the neighbors of the value at index in the original array. If this function would result in returning garbage values the new array should be set to values {0,0} instead of values from the array.

### Explanation
This C++ code snippet demonstrates the concept of retrieving neighboring elements from an array. The function `getNeighbors` is designed to return a pointer to the neighbor values of a given element.
- The array `a` is initialized with the values `{1,2,3,4,5}`.
- `getNeighbors(a, SIZE, 3)` retrieves neighbors of the element at index 3.
- `print(b, 2)` prints the retrieved neighbors, leading to the output `3 5`.
- `getNeighbors(a, SIZE, 0)` retrieves neighbors of the element at index 0.
- `print(c, 2)` prints these neighbors, resulting in `0 0` since there are no valid neighbors.
This specific implementation of the function `getNeighbors` is not shown, but the outputs suggest that it handles out-of-bounds indices by returning zeros.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2Ff5d50b6e-7a61-46d2-80da-1b780938b575%2F9b81ce3d-4b4c-4063-9a23-f128fa0b7b95%2Fxzikmz_processed.png&w=3840&q=75)
