Thanks to the students who attended today (their emails are in the file
11.04.attend.txt)

Question: If I want a command line such as:


 ./myprog inputFile.txt

or
 ./a.out students.data

WHY use: 

 if (argc!=2)

Why not: 

 if (argc!=1)


Answer: 

   argc counts how many arguments are on the command line.
   ./a.out students.data has TWO arguments not one.

   Two arguments are numbered argv[0] and argv[1].


Remember to 

#include <fstream>

when using ifstream objects to read data from external files.
