A Stream is a sequence of bytes.

The fflush() function writes any buffered data to the specified file stream. When you write data to a file (with a function such as fprintf()), it is actually placed in a memory buffer. The data is only actually written to the file when the buffer is full, the file stream is closed or when fflush() is called.
The term stream is a generic abstraction that says nothing about the implementation. However, if we use the analogy that gave it its name, a stream of water, we can better understand how a stream works. A water stream allows water to flow from one point to another in one direction only (downstream, with the flow of the current). If we were to throw a stick into the water, it would be carried downstream by the water where it could then be extracted. Sticks can be inserted or extracted automatically by devices, thus allowing information to pass between those devices.A file stream is a stream that is associated with a device representing a file. If the file is upstream then we can use the stream to extract information from the file. When we extract information from a stream, that stream is known as an input stream; it provides us with information. Conversely, if the file were downstream then we can use the stream to insert information into the file. When we insert information into a stream, that stream is known as an output stream; it carries information away from us.An input/output stream is one where we can both insert and extract information. An input/output file stream is a typical example: we can extract data from the file associated with the stream, process the data (modify it in some way), and then insert the modified data back into the same file. To implement an input/output stream, we simply use two streams associated with the same device: one specifically for input operations, the other specifically for output operations. This implementation detail is hidden from the user, so the stream appears to be a bi-directional stream as far as the user is concerned.
Files don't have a data type. Functions, classes, enumerations and variables are all examples of data types. We may use a stream to represent a file, but a stream is no more a file than a file is a stream. A stream is merely an abstraction that can be used to represent any device that requires buffered input and/or output of character sequences.
A stream is how a program reads to and writes from a file. When a program needs to create or edit a file, it opens up a "stream" to the file, "streams" the intended data to the file, and then saves it before closing the stream.

writes data to a FILE* stream.
File handling is handled by input stream objects (ifstream) and output stream objects (ofstream), or bi-directional streams (fstream). These classes are derived from istream and ostream. See related links for more information on these classes.

You can use fstream header file to read and write in files. It has two main components ifstream: stream which you can use to read data, and ofstream which allows you to save in files. Use something like this:#include#includeusing std::ifstream;using std::cout;using std::endl;int main(){char fileName[] = "myfile.txt";//file to read fromifstream inData;//stream to read from myfile.txtint data = 0;//to read one number of type int (we assume that the file contains it)inData.open(fileName);//connect the stream to the fileif (inData.fail())//if coult not open the file, program will be closed{cout data;//read one number from the file and save it in data of type intcout
I don't know of an official printer file format. However, if you print to file, the data stream is saved as the .xps format. Perhaps this is what you are looking for.
The ASF file format system, also known as "Associated Streaming Format" is used to compose data stream in a file. They compose data streams in files like HTML or MPEG4.
There is something called a workbook dump. It is excel-based, and can be used to export data from HySYS to excel.
