INHERITANCE AND FILE HANDLING IN C++2
Instruction on using the program:
The program can be run from any computer that has gcc installed in it. Even light IDE
(Integrated development environment) like Code Blocks can also be used. One thing that
should be considered is, during the first run if you wish to view the results, then the csv
(deviceService.csv) file must be kept in the same folder to that of the running program
otherwise an error message will be displayed stating “File not found”. On the oyher hand if
you wish to create the csv file from the beginning, then there is no need to keep the supplied
csv file in the ‘.cpp’ file location. Upon going through data insertion process properly, the csv
file will be automatically created by the code.
If you want to open the visual studio project and run the program there, then latest
version of Visual Studio is preferred (Visual Studio 2019) with C++ installed in it.
Following are the written codes and outputs with some error handling:
Code

#include <string>
#include<fstream>
