Program $02$: using C$++$

You need to write a $C$ program that prompts an instructor to enter the numeric

grades earned by a student and calculate the average score and course grade for

the student. You should use a $\text{'}$do while' loop and a 'switch' statement.

You need to ask the instructor how many grades they are going to enter for the

student. Then, use a loop to prompt the instructor to enter the individual

numeric grade earned by the student. After the loop has finished, you need to

calculate the average grade $($this is the accumulated total number of grades

entered by the instructor divided by the number of grades entered$).$ Then you

should use a Switch statement to get the letter grade earned by the student $($Hint:

in the Switch statement, you will need to use the following: $($int$)$averageGrade $/$the number of grades entered$).$ Once you exit the Switch command, you need to

display the average grade and the grade received.

For example, if the user chooses to enter $4$ exams, and the four grades for the

exams are $80,50,60,$ and $90,$ the average grade should be a $70$ and the grade

received should be a $C.$
