This is a program that would help you to learn about the basics of a file through c++. This would teach ue that how can we acess a file, of how can we open it, how can we cloase it, how can we acess the documents present in a file. Its easy to use just install a c++ compiler copy this program to a new notepad and save it as a .cpp file and copy it in the bin of c++ compiler. Its all done now just open compiler search for the file open it and run it.
