Problem 1

• Many universities send warning notices to
  freshmen who are in danger of failing a class.
  Your program should calculate the average of
  three test grades and print out a students ID
  number, average, and whether or not the student
  is passing. Passing is a 60-point average or
  better. If the student is passing with less than
  a 70 average, the program should indicate that he
  or she is marginal.

Problem 1

• Input student ID number followed by three test
  grades. The student ID number is of type long to
  accommodate larger values such as nine-digit
  social security numbers.
• Output
• Echo print
• ID, average grade, passing/failing, marginal, and
  error message if any of the test scores are
  negative.
