---+Lab 4 for CSC 121
---++Overview
For this lab you are to write a program that assigns a letter grade to an exam passed on the statistics for the entire class.  The details are below
---++Details for computing
ST stands for standard deviation.  ME is the mean<br>
An A is any grade that is > ME + 1.5*ST<br>
A B is any grade that is > ME + 0.5*ST and <= ME + 1.5*ST<br>
A C is any grade that is > ME - 0.5*ST and <= ME +0.5*ST<br>
A D is any grade that is > ME -1.5*ST and <= ME - 0.5*ST<br>
An F is any grade that is <= ME-1.5*ST<br>

---++Details for the program
You are to get a series of numbers (floating point) from the user for a class (terminated by a -99).  For each grade, print out the letter grade associated with that value based on the above formulas.
---++For those that want a challenge and have successfully completed the above
Figure out how to read the grades from a file using the end of file to signal the end of the data.  This is to be done on your own without help from any other person -> you can use the textbook only.
