Rewrite this program using C++ Vectors!!! - Show program work - Ill rate the best answer

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

Write a C++ program that reads a list of double-precision grades from the keyboard into an array named grade. The grades are to be counted as they are read, and entry is to be terminated when a negative value has been entered. After all grades have been inputted, the program should find and siplay the sum and average of the grades. The grades should then be listed with an asterick (*) placed in fron of each grade that is below the average.

Also display each grade and its letter equivalent, using the scale:

Between 90 and 100 = A

Greater than or equal to 80 and less than 90 = B

Greater than or equal to 70 and less than 80 = C

Greater than or equal to 60 and less than 70 = D

Less than 60 = F
