Explanation:

Your question is poorly formatted. (See attachment for proper presentation of question)

------------------------------------------------------------------------------------------------------------

The first step is to go to the main function and replace

//TODO: Add function calls

with the following 4 lines of code:

getGrades(grades,SIZE);

average = getAverage(grades,SIZE);

countLetterGrades(grades, SIZE, numberOfAs,numberOfBs,numberOfCs,numberOfDs,numberOfFs);

printData(average, numberOfAs,numberOfBs,numberOfCs,numberOfDs,numberOfFs);

------------------------------------------------------------------------------------------------------------

1. getGrades(grades,SIZE);

This calls the getGrade functions; The getGrade function is where the user inputs 5 grades for a student

2. average = getAverage(grades,SIZE);

Next, is to get the average of the input grades. This is done using the above and the average is stored in variable average

3. countLetterGrades(grades, SIZE, numberOfAs,numberOfBs,numberOfCs,numberOfDs,numberOfFs);

Next, is to get letter grade of each number grade. This is done using countLetterGrades function.

4. printData(average, numberOfAs,numberOfBs,numberOfCs,numberOfDs,numberOfFs);

The above 3 functions populate data for average, numberofAs to numberofFs; This values are passed to printData function to to display program output.
