   la -a      
         show all files

   ls -l
         show attribute information on the files

3.  Editing

   vi and nano editors 

4. Compilation in C/C++

   g++ file.cpp

      Translate the C/C++ source code contained in the file file.cpp
         into the machine code in the file a.out

  Program development includes
    1.   Editing the program    ( nano file.cpp )
    2.   Compiling the program  ( g++ file.cpp )
    3.   Run/executing the program   (./a.out  )
    4.   Repeat as needed

5.  To run/execute the program, the computer needs to run the
       machine code

   ./a.out

        ./    look in the current directory 
  

6.   Mail the program to yourself

    mail -a file.cpp  troy@uic.edu
