Problem Statement - Empty File Creation
Creating an empty file using ofstream class
Learning to use ofstream class in its simplest form.
Learning to use the close() method of ofstream class.
File Created Successfully
#include <iostream> #include <fstream.h> //This header file is required for data file handling classes
using namespace std;
For using creation of a file we use ofstream class (output file stream) with filename as parameter. This will create a file on the disk without any content (empty file). fout is the object name selected by us. we can give any name to this object.
cout<<“File Created Successfully”<<endl;
Displays that file has been created.
Here we are using the close method of ofstream along with the object name prefix.
This is the simplest way of creating a file, but for practical purposes we must check if the file has been created.
one can also make this program using fstream class which has capability of using both in input as well as output mode.
It is important to give file name as string literal or a null terminated pre-initialised char array.
