For the file opening, a file stream must be create and then it should be linked to the filename. The file stream can be defined using the classes ifstream ofstream and fstream that are contained in the header file fstream.h. The class to be used depends up on the purpose, that is whether the file is opened for reading or writing data. A file can be opened in two ways. Using the constructor function of the class. Using the member function open() of the class.

Example

ofstream outfile;                  // create stream (for output)
outfile.open ("file 1")              // connect stream to file 1
outfile.close();                     //Disconnect stream from file 1
outfile.open ("file2")              //Connect stream to file2
outfile.close();                     //Disconnect stream from file2
