C dynamic memory allocation refers to performing dynamic memory allocation in the C programming language via a group of functions in the C standard library, namely malloc, realloc, calloc and free.
The C++ programming language includes these functions for backwards compatibility; its use in C++ has been largely superseded by operators new and new.
Many different implementations of the actual memory allocation mechanism, used by malloc, are available. Their performance varies in both execution time and required memory.

Famous quotes containing the words dynamic and/or memory:
“The nearer a conception comes towards finality, the nearer does the dynamic relation, out of which this concept has arisen, draw to a close. To know is to lose.”
—D.H. (David Herbert)
“When he became all eye when one was present, and all memory when one was gone; when the youth becomes the watcher of windows, and studious of a glove, a veil, a ribbon, or the wheels of a carriage, when no place is too solitary, and none too silent.”
—Ralph Waldo Emerson (1803–1882)
