Exactly 700 student interviews were conducted with the information being placed in a file named studentsurvey.txt  Each line of this file contains a student's age, grade point average (GPA), number of credits being carried, a 3- or 4-letter designator of the student's major and seven indicators as to what the student was doing each night of the survey week at 9 pm.  The indicators are in order, representing the nights of Sunday through Saturday).  The indicators consist of 2-letter codes, as follows
 

Only traditional college students were surveyed; thus, the ages are limited to between 18 and 23 years old.  Also, only full-time students were surveyed; thus, the number of credits they were taking ranged between 12 and 19.  There is no particular order to the data in the studentsurvey.txt file.  Below are the first few lines of the file

You are to write a C++ program that reads the studentsurvey.txt file and produces two reports about what the students were doing at 9 pm on whatever night of the week the person running the program selects.  That is, the program should prompt for a day name and expect the person at the keyboard to enter "Sunday, Monday, . . . or some other day" and then display the two reports.  These reports are often referred to as cross-tabulations.  One report is to show the number of students by credit load and 9 pm activity - so that we can see how many students with a 12-credit load were watching TV, studying, listening to music, etc. (and the same for 13-credit loads, 14-credit loads, etc.).  The other report is to show the number of students by GPA group and 9 pm activity.  The GPA groups are for GPAs less than 2.0, >= 2.0 and < 2.5, >= 2.5 and < 3.0, >=3.0 and < 3.5, and >= 3.5.  Thus, we can see how many students with a GPA < 2.0 were talking on the phone, using a computer, drinking, etc. (and similarly for the other GPA groups).   Below is a sample of the output for Wednesday activity.

Your program should be designed so that the person at the keyboard may enter any day of the week and get a listing for that day; then the program should prompt for another day.  When the person at the keyboard enters "end", the program should  quit.  Your program MUST use at least one 2-dimensional array or an array of  structs or both.

You can get your copy of studentsurvey.txt from the jlwolfe\110 folder on the I: drive.  Hand in a printout of your program and a printout of the complete results if the person at the keyboard enters Tuesday as the day of the week and then enters Saturday as the day of the week.  Name your .cpp file after yourself (as in yourname.cpp) and copy it to the hand-in folder for the course on the P: drive.

For extra credit:
1.  Show a table of student age vs 9 pm activity similar to the two that you are required to produce.  This is fairly easy to do.
2.  Show a table of major vs 9 pm activity similar to the two that are required to produce.  This is fairly difficult to do.
