Consider a comma-separated file that contains student names and scores such as the following: Jane Lee, 100, 98, 97, 100 Aaron X. Schmidt, 37, 42, 49, 54 Frank von Tardy, 2, 3, 10, 7 We can read the file one line at a time and use an istringstream object to process the scores. To get the position of the first comma, simply read words from the input stream until the word ends with a comma. Then, read and sum the numbers remaining on the line. Use get to remove the commas following each number. Rearrange the lines below to compute the total score for a single student. Assume that each student has at least one score.

Jane Lee, 100, 98, 97, 100
Aaron X. Schmidt, 37, 42, 49, 54
Frank von Tardy, 2, 3, 10, 7
We can read the file one line at a time and use an istringstream object to process the scores. To get the position of the first comma, simply read words from the input stream until the word ends with a comma. Then, read and sum the numbers remaining on the line. Use
get to remove the commas following each number.
Rearrange the lines below to compute the total score for a single student. Assume that each student has at least one score.
