  /**********************************************************
 * Program to interactively ask the user to provide
 * a file name, and then do following tasks.
 *
 *   1. open to file to read
 *   2. count the number of lines in the file.
 *   3. display file and the count of lines.
 *   4. Repeal until user ends the program.
 
 // to open a file there are two ways
 //1.Put the file inside the project where the main.cpp file exists
 //then when the program ask you to enter a file name, you need
 //to write a file name that you had written in the main.cpp file exists somefile.cpp
 //for example: "somefile.cpp" and you write (string fileName = "somfile.cpp";) inside your int main( ) code
 
 //2. Another way is using absolute path: say you have a file somefile.cpp
 //or somefile.txt or any fileÖ in c drive, then enter c:/somefile.txt ÖÖetc.
