The friend declaration appears in a class body and grants a function or another class access to private and protected members of the class where the friend declaration appears. Syntax friend function-declaration (1) friend function-definition (2) friend elaborated-class-name ; (3) friend simple-type-specifier ; friend typename-specifier ; (4) (since C++11) Description 1) Designates a function or several functions as friends of this class class Y { int data;

A ForwardIterator is an Iterator that can read data from the pointed-to element. Unlike InputIterator and OutputIterator, it can be used in multipass algorithms. Requirements The type It satisfies ForwardIterator if. The type It satisfies InputIterator The type It satisfies DefaultConstructible Objects of the type It provide multipass guarantee described below The type std::iterator_traits<It>::reference must be exactly T& if It satisfies OutputIterator (It is mutable)

Executes init-statement once, then executes statement and iteration_expression repeatedly, until the value of condition becomes false. The test takes place before each iteration.

Requirements A FormattedInputFunction is a stream input function that performs the following: Constructs an object of type basic_istream::sentry with automatic storage duration and with the noskipws argument set to false, which performs the following if eofbit or badbit are set on the input stream, sets the failbit as well, and if exceptions on failbit are enabled in this input stream's exception mask, throws ios_base::failure. flushes the tie()'d output stream, if applicable if ios_b

Requirements A FormattedOutputFunction is a stream output function that performs the following: Constructs an object of type basic_ostream::sentry with automatic storage duration, which performs the following if eofbit or badbit are set on the output stream, sets the failbit as well, and if exceptions on failbit are enabled in this output stream's exception mask, throws ios_base::failure. flushes the tie()'d output stream, if applicable. Checks the status of the sentry by calling sent
