c++ program to write the grades on a file the names of the files are shown in the picture

here is my complete question

There are a couple of approaches you can take for this o Method 1 . Load the line into a stringstream . Use the overload of getline that takes an optional delimiter. This causes getline to read up to a comma instead of a newline o Method 2 . Use use.find to find commas, then use substr to extract substrings from in between those commas Once you have extracted the scores as strings, you will have to convert them to ints For this you can use either stoi (string to int) or a tring tream Input rawgrades-bw101.csv Your output Your program produced no output Name Scores (Low) Total Average Grade Fred Flintstone Barney Rubble Yogi Bear Secret Squirre.l Dick Dastardly 70 82 55 80 55) 65 62 0 71 0) 89 92 100 95 89) 75 7783 81 75) 59 0 37 0 0) 232 198 287 241 96 77.33 66.00 95.67A 80.33 32.00 Expected output 10: Star Wars-Report 0/5 Could not find file: grade-report-starwars.txt Input rawgrades-starwars.csv Your output Your program produced no output Name Scores (Low) Total Av erage Grade 272 282 239 90.67 94.00 79.67 300 100.00 300 100.00 83.67 Luke Skywalker Leia Organa Han Solo 88 97 87 84 84) 94 100 88 83 83) 87 69 18 83 18) 100 100 100 99 99) 100 100 99 100 99) 95 2789 67(27) 98 93 96 97 93) 37 50 3 0 0) Expected output Threepio Artoo Darth Vader Ben Kenobi Jar-Jar Binks 251 291 90 97.00A 30.00 Starter Code nput File Format Output File Format Output File Format aerage and 515 5 2 31 66.0 mplementing the helper functions The Top-Level Functions bool openFiles(..)
