/*
The useful classes for working with files in C++ are:
1. fstreambase
2. ifstream --> derived from fstreambase
3. ofstream --> derived from fstreambase
*/
// In order work with file in C++,you will have to open it.primarily, there are 2 ways to open a file:
// 1. Using the constrctor
// 2. Using the member function open() of the class
using namespace std;
