Question: 1 / 565

What does the 'std' namespace represent?

Standard Directives

Standard Library

The 'std' namespace stands for standard library, which is a collection of pre-written classes, functions, and constants that can be used in C++. This library contains many useful functions and classes, making it easier for developers to write code without having to create everything from scratch. Option A, Standard Directives, is incorrect because the 'std' namespace does not contain any directives. Option C, Standard Language, is also incorrect because the 'std' namespace is specific to the C++ programming language. Option D, Structured Data, is incorrect because the 'std' namespace is not limited to just structured data, but includes various types of functions and classes. Therefore, option B, Standard Library, is the correct representation of the 'std' namespace.
