Arrays as function arguments

The program given below is a revision of the previous array lab. In this assignment you are to make changes in

your code for GPA to use functions and pass an array as a function argument. You are also asked to find the largest

value in the array.

Input is from a file, output is to a file.

Write a function to print the headings.

Write a function to find and return the largest value in the array. The function shall have two arguments: the

array of grades and an integer giving the count of the number of values in the array. The largest grade shall

be returned through the function name $($return statement$).$

Write a function to write out the grades and the largest grade. The function shall have three parameters: the

output file object, the array of grades, an integer giving the count of the number of values in the array, and

the largest grade.

Test the code with the test data: $89,67,93,78,95,77,88,65,91,68,71,86$

Use the following list of changes to the previous GPA pseudocode

Create a function to print the headings into the output file.

Add a function to find and return the largest value in the array.

Output is now:

a$.$ Print the grades from the array.

b$.$ Print the average$|$

c$.$ Print the largest value.

Output:

GPA
