We will start by finding the largest value. Initially, we assume that the first element in the list is the largest element and create a variable maxValue that is initialized to the first element in the array. We then compare the element that maxValue is storing with every element in the list. Whenever we find an element in the array larger than the element that maxValue is storing, we update maxValue so that it stores the value of the newer larger element. Algorithm ArrayLargestElement Declare and initialize maxValue to the first element in the array. Use a FOR loop to traverse the array. // You already checked the first element, so you should start the loop at the second element. If the element at this index is larger than maxValue Update maxValue Output maxValue. Write a program MyArray_ABC that declares an array containing the following elements: 45, 38, 27, 46, 81, 72, 56, 61, 20, 48, 76, 91, 57, 35, and 78, and outputs the largest value. PART B. Modify the program described above so that it outputs the index where the largest value is positioned. Use a variable maxIndex to store the location. PART C. Include in the program described above a variable sum that, while traversing the array to find the largest element, sums up all the elements and outputs the result. PART D. Create a new class MyArray_DE and copy and paste the previous program. Be sure to rename the class to MyArray_DE. Modify the program so that it sums up only the even numbers. PART E. At the end of the program, write a FOR loop that prints the array in reverse (you are not reversing the array; you are simply printing it). Test your program with all the above test cases.

We will start by finding the

largest value. Initially, we assume that the first element in the list is the largest element and create a variable maxValue that is initialized to the first element in the array. We then compare the element that maxValue is storing with every element in the list. Whenever we find an element in the array larger than the element that maxValue is storing, we update maxValue so that it stores the value of the newer larger element. Algorithm ArrayLargestElement Declare and initialize maxValue to the first element in the array. Use a FOR loop to traverse the array. // You already checked the first element, so you should start the loop at the second element.

If the element at this index is larger than maxValue Update maxValue Output maxValue. Write a program MyArray_ABC that declares an array containing the following elements: 45, 38, 27, 46, 81, 72, 56, 61, 20, 48, 76, 91, 57, 35, and 78, and outputs the largest value.

PART B.

Modify the program described above so that it outputs the index where the largest value is positioned. Use a variable maxIndex to store the location.

PART C.

Include in the program described above a variable sum that, while traversing the array to find the largest element, sums up all the elements and outputs the result.

PART D.

Create a new class MyArray_DE and copy and paste the previous program. Be sure to rename the class to MyArray_DE. Modify the program so that it sums up only the even numbers.

PART E.

At the end of the program, write a FOR loop that prints the array in reverse (you are not reversing the array; you are simply printing it). Test your program with all the above test cases.
