Question

1. What is the purpose of the variable errno? What kind of variable is it? 2. What does buffering refer to? Why is it used? 3. How do text streams and binary streams differ? What are the advantages and disadvantages of each? 4. What are stdin, stdout, and stderr?

Answer 1

1. A variable is nothing but a name given to a storage area that our programs can manipulate.

2.In web based sound or video from the Internet, buffering alludes to downloading a specific measure of information before beginning to play the music or film. ... See real time video and versatile real time. Buffering Over the Internet. In the event that an organization is sufficiently quick to stay aware of playback, buffering isn't essential.

PCs have various gadgets that all work at different paces, and a support is expected to go about as such a brief placeholder for everything and same with online recordings.

3.

Text Streams

The Text information type speaks to character information put away in an information backing store, for example, a book document or a book segment. You can peruse text from an information backing store utilizing the TextReader class and compose text to the information backing store utilizing the TextWriter class.

Binary Streams

A binary file is a file encoded in a binary format and the data is stored as a series of bytes. Binary files can contain images, sounds, text or compiled code. The BinaryReader and BinaryWriter classes are designed for reading and writing binary.

BinaryReader and BinaryWriter

The BinaryReader and BinaryWriter classes are used to read and write data in binary files. The class reads and writes data types as binary values. These classes are used to read and write binary files that can be shared with applications that process binary data.

4.

stdin-Standard input - this is the file handle that your process reads to get information from you.

stdout-Standard output - your process writes conventional output to this file handle.

stderr-Standard error - your process writes diagnostic output to this file handle.

every answer is explained well hope you will understand
