I am having a difficulty with this problem? ```cppint a[][COLS] = { { 3, 1, 4 }, { 1, 5, 9 } };cout << even_elements(a, 2) << endl;cout << "Expected: 1" << endl;int b[][COLS] = { { 3, 1, 4 }, { 4, 1, 1 }, { 5, 9, 10 } };cout << even_elements(b, 3) << endl;cout << "Expected: 3" << endl;int c[][COLS] = { { 3, 1, 4 }, { 1, 5, 9 }, { 2, 6, 5 }, { 1, 3, 6 }};cout << even_elements(c, 4) << endl;cout << "Expected: 4" << endl;return 0;```### Testers**Running Tester.cpp**- fail fail fail```0Expected: 10Expected: 30Expected: 4```### AnalysisIn the provided C++ code, there are three test cases that employ a function named `even_elements()`. This function intends to count the even numbers in 2D arrays (`a`, `b`, and `c`). The program outputs the actual count and displays the expected count for comparison. However, all test cases fail, indicating discrepancies between the actual and expected results. The function likely needs debugging or correction to meet the expected outcomes. ## Count How Many of the Elements of the Given Two-Dimensional Array Are Even### tables.cpp```cppconst int COLS = 3;int even_elements(int values[][COLS], int rows){ int count = 0; return count;}```### Tester.cpp```cpp#include using namespace std;const int COLS = 3;int even_elements(int[][COLS], int rows);int main(){ int a[][COLS] = { { 3, 1, 4 }, { 1, 5, 9 } }; cout << even_elements(a, 2) << endl; cout << "Expected: 1" << endl; int b[][COLS] = { { 3, 1, 4 }, { 4, 1, 1 }, { 5, 9, 10 } }; cout << even_elements(b, 3) << endl; cout << "Expected: 3" << endl;}```### ExplanationThis code aims to count the number of even numbers in a two-dimensional integer array. The function `even_elements` is defined but not yet implemented to complete this task. Two arrays are tested in the `main` function. - **Array `a`** has 2 rows: `{ 3, 1, 4 }` and `{ 1, 5, 9 }`. It should have 1 even number, `4`.- **Array `b`** has 3 rows: `{ 3, 1, 4 }`, `{ 4, 1, 1 }`, and `{ 5, 9, 10 }`. It should have 3 even numbers, `4`, `4`, and `10`.The code includes `cout` statements to display the results and the expected outputs.### Graphs or DiagramsThere are no graphs or diagrams in this image.
