write a program to read an unknown number of scores (double type) from the keyboard and calculate the sum and average (mean) of the scores.

Question

write a program to read an unknown number of scores (double type) from
the keyboard and calculate the sum and average (mean) of the scores. The program will repeatedly
read scores until a non-number is entered.The program should then output the sum and the average
of all of the numbers to the screen to an accuracy of 2 decimal places.
You don't need to use an array to store all of the scores (we haven't learned about arrays yet,
but most importantly, it is not necessary). Use variables to store the sum and number of scores you
read and calculate the average after the user enters the non-numeric value
