Input and Output I

Flashcards covering key concepts related to input, output, namespaces, strings, and stream manipulation in C++.

Namespace

A space to hold different identifiers like function names, object names, class names, etc. It prevents naming collisions by allowing the same name to be defined within different namespaces.

std::string

The C++ string data type in its standard library that represents a sequence of characters.

Append

Compare

Get length

An operation on strings to retrieve how many characters are within the string.

Indexing

An operation on strings to target certain characters.

The standard header that contains the delcarations of the standard input and standard output.

std::cin

Standard input stream in C++ used to read input from the terminal.

std::cout

Standard output stream in C++ used to display output to the terminal.

std::endl

Inserts a new-line character and flushes the output stream.

getline(stream, variable)

A function that reads an entire line from the input stream.

cin.get()

A function that allows you to get one character at a time from cin.

cin.ignore(size)

A function that is used to ignore a certain amount of characters specified by size.

cin.ignore(size, delim)

A function that is used to ignore a certain number of characters specified by size or until it hits the delimiting character.
