C++ Input/Output Operations

It contains definitions of objects like cin, cout, cerr, etc. for standard input-output operations.

To avoid having to write STD:: before standard library functions, allowing direct access to them.

It is used for printing outputs.

<p>Dynamic binding in C++ is a process where the code to be executed in response to a function call is decided at runtime. This is different from static binding, where the function call and definition are connected at build time. Dynamic binding is flexible and uses virtual functions to support this.</p> Signup and view all the answers

<p>Objects communicate with each other by sending and receiving information, known as message passing. This involves specifying the name of the object, the name of the function, and the information to be sent.</p> Signup and view all the answers

<p>In input streams, the direction of flow of bytes is from the device (e.g., keyboard) to the main memory. In output streams, the direction of flow of bytes is from the main memory to the device (e.g., monitor).</p> Signup and view all the answers

<p>Inheritance is a mechanism in object-oriented programming where a new class (derived class) inherits the properties and behavior of an existing class (base class). This allows for code reuse and facilitates the creation of new classes.</p> Signup and view all the answers

<p>C++ provides libraries that offer various ways to perform input and output operations. These libraries enable the manipulation of input and output streams, allowing for reading and writing data to and from devices.</p> Signup and view all the answers

<p>An input stream is a sequence of bytes flowing from a device (e.g., keyboard) to the main memory, whereas an output stream is a sequence of bytes flowing from the main memory to a device (e.g., monitor).</p> Signup and view all the answers
