Open the attached .cpp file. Fill in the two missing functions where it says insert code here. Everything else has been written for you to test your functions. You may not change anything in the file other than write the functions. Note: For testing purpose, I will have different data in file numbers. txt. Expected Output: Data in file: 10

Sum of all even numbers in list = 130
List after deleting even numbers: 9

HERE IS THE CPP:
/*This program is your final exam.
All you need to do is to fill both the functions.
1) Find the sum of the even numbers in the list.
Please insert code in the function called int sumEven(int[], int)
2) Delete/Remove all even numbers in the list.
Please insert code in the function called void delEven(int [], int &)
Note: Even if I change the content of the input file, your program should still produce the correct output.
