Scores.txt :

10 20 30 40 50 60 -999

scoresout.txt :

45 55 65 75 85 95 -999

Write a program that reads in integer numbers from a file called scores.dat or scores.txt until the sentinel value -999 is read. The program should then output the total and average of the numbers read and output each of the numbers incremented by the overall average to a file called scoresout.dat or scoresout.txt along with then sentinel value of -999 at the end So if 10, 20, 30 and-999 are read in then the program would display a total of 60 and an average of 20 then output to the scoresout.dat file 30, 40, 50 and -999 Hint: So read the input file, calculate the total and the average, display them to the sreen then save them to separate variables and close the input file. Re-open the input file, open the output file, take each number from the input file, add the average to it then output it to the output file (except don't add the average to -999). A little trickier than I originally had thought but I think you can handle it.. Use good variable names and make sure your information prompts and output display items are full statements that ask a question and give a complete
