A simple grade book program: An introduction to c++ using vectors

Programming class grade rosters Objective: To input a class roster and compute each students average grade assigning a letter value. Write a program that has the user input a students name followed by grades for a set of assignments. input should start with the students name. Subsequent values should be numbers for each assignment. Rules: o Your program should allow a name of unlimited length (use the String class). o You must use at least 2 functions. One or more must be used to input a row of data. One (or more) must be used to output data. o MUST USE VECTORS, do not declare the length/size of the vectors. o input lines will appear all on one line (to determine when one student is finished and the next started, you can either assume the carriage return denotes the end of the input for that student or assume that non-numeric input is the next student's name (negative grades, if provided, should be ignored) o the "KEY" may appear on any line. Input stops at the end of the file (if taking input from command line, Control-D should send your program the EOF signal) o You must demonstrate your program using the test cases shown here.
