What is the standard stream that you read input from?
The standard console input stream, std::cin.
What are input output streams in c plus plus?
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.
What is the extraction operators in C plus plus?
This operator (>>) applied to an input stream is known as extraction operator. It performs an input operation on a stream generally involving some sort of interpretation of the data (like translating a sequence of numerical characters to a value of a given numerical type).Three groups of member functions and one group of global functions overload this "extraction operator" (>>) applied to istream objects:The first group of member functions are arithmetic extractors. These read characters from the input data, and parse them to interpret them as a value of the specific type of its parameter. The resulting value is stored in the variable passed as parameter.The streambuf version copies as many characters as possible to the stream buffer object used as right-hand parameter, either until an error happens or until there are no more characters to copy.Those in the last group of member functions have a pointer to a function as parameter. These are designed to be used with manipulator functions. Manipulator functions are functions specifically designed to be easily used with this operator.The global functions overload the operator when the parameter is either a character or a c-string, and, as expected they extract either one character or a sequence of characters from the input stream.
What is the input statement for a program?
Input statements extract data from an input stream. For example: int x; std::cin >> x; Output statements insert data to an output stream. For example: std::cout << x; You cannot insert data into an input stream and cannot extract data from an output stream. However, streams that are both input and output streams (such as read-write files) can insert and extract data as required, depending on whether you are reading or writing to the stream.
What are the uses of File Input Stream and File Output Stream in java programming?
These streams are classified as mode streams as they read and write data from disk files. the classes associated with these streams have constructos that allows us to specify the path of the file to which they are connected. The FileInputStream class allows us to read input from a file in the form of a stream. The FileOutputStream class allows us to write output to a file stream. Example, FileInputStream inputfile = new FileInputStream ("Empolyee.dat"); FileOutputStream outputfile = new FileOutputStream ("binus.dat");
What is the standard stream that you read input from?
The standard console input stream, std::cin.
Is an ROM an input or output?
It is an input as the longer version of CD-ROM is Compact Disk - Read Only Memory, it can only be described as an input.
Is a CD-ROM an input device?
I would say that a CD-ROM is a form of input, as it is "read only memory" and the data on it can only be read, but not written to. If you're talking about CD-R/CD+R drives, then those would be considered both input and output, as it can read from a CD, and writes to CD.
What is input stream reader?
In general terms, an input stream reader in Java is a program or class used to read an input stream as a sequence of characters (as opposed to bytes). A stream is an I/O connection to an external resource such as a file, socket or URL, that exchanges bytes with that resource. "Input" refers to the fact that the information flows from the external resource into the program. A reader translates a byte sequence into characters (more precisely, Unicode code points) according a particular encoding. Specifically, the class java.io.InputStreamReader is a reader that can convert any instantiated input stream into characters according to a particular encoding. <http://download.oracle.com/javase/7/docs/api/java/io/InputStreamReader.html> <http://download.oracle.com/javase/tutorial/essential/io/fileio.html> Always read the documentation!
What is ROM BOIS?
Its an input and an output button OR It,s the basic input and output of a read only memory

C plus plus reading and writing a file?
Use an input file stream (ifstream) to read from a file and an output file stream (ofstream) to write to a file. Both can be found in the <fstream> standard library header.
Is read denominator a input?
It can be an input.
