Checkoff

If you are writing a program that will be used a lot, it is good practice to write it so that it catches and reports I/O errors of the sort described in this lesson.

Modify the program that you wrote to check off the last lesson so that it can deal with an input file with any number of lines. It should

• report a problem and stop if the input file does not exist, and

• report a problem and skip over any input line that is badly formatted.

Remember--your last line of data must be followed by a newline!
