What are Streams?

4.
What are Streams?
When data is sent from one program or peripheral devices to another program or
output device, it is known as a stream.

5.
What are Streams?
The main mechanism for exchange of information in the world of computers is streams.

6.
What are Streams?
Many operations in the realm of computers may be seen as reading from and writing to
a stream.

7.
What are Streams?
Every time you read from or write to a file, you must first open a stream to that file,
perform the read and write, and afterwards close the stream.

Binary Stream

11.
Binary Streams
One or more bytes of arbitrary data make up a binary stream.

12.
Binary Streams
The bytes sent between the program and a binary stream are not changed by the
library functions.

13.
Binary Streams
With the exception of location in relation to the end of the stream, positioning within a
binary stream is well-defined.

14.
Binary Streams
A file is viewed as a series of bytes in a byte stream.

15.
Text Stream

16.
Text Streams
One or more lines of text that may be written to a text-oriented display and viewed
together make up a text stream.

17.
Text Streams
The software reads an NL (newline) at the end of each line while reading from a text
stream.

18.
Text Streams
The application uses an NL to indicate the end of a line when writing to a text stream.

19.
Text Streams
Positioning is constrained inside a text stream. Calling fgetpos or ftell will return the
current file-position indication.
