Difference between input stream class and writer class?
The InputStream is an abstract class of the type input stream class. Every other input stream class is a sub class of InputStream class. Various methods defined therein to perform functions such as reading data bytes, closing streams, marking position in a file. On the other hand, The Writer class is an output stream that supports writing of Unicode characters. It is an abstract class that cannot be directly instantiated. Its subclasses inherit all its properties of writing data characters, using output stream, into the data files. by Raaj.1971 at the rate of yahoo dot com
Explain the input stream and output stream class hirerarchies with suitable diagrams?
The diagrams can be made off the description that you are able to give. Make them both as detailed as you are able to.
Which stream functions in c plus plus control the formatting of input and output values of a class?
None of them. To control the formatting of your classes, you must overload the stream insertion and extraction operators.
What is the ideal dc value of output signal when there is no input signal in class b amplifier?
A: If the input is zero the desire output is zero no matter what class it is.
Identify the class of a lever for which does function is between the input force and the output force?
The third class lever functions between the input force and the output force
What is meant by input stream?
An input stream is a character sequence device or buffer from which input can be gathered. The standard input stream is usually a keyboard, data file or the output stream from another program. The user of the program can normally decide where standard input may be redirected from when launching the program, typically defaulting to the keyboard.
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 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 is stream operator in c plus plus?
There are two stream operators: << (insert or put) and >> (extract or get). Output streams implement the insertion operator, input streams implement the extraction operator and input/output streams implement both operators.
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.
Identify the class of lever for which the fulcrum is between the input force and the output force?
2nd class
What is the use of printf and scanf function?
Printf prints something to the standard output stream, and scanf inputs something from the standard input stream.
