In C++, this ability is put to further use to automate memory deallocation within an otherwise-manual framework, use of the shared_ptr template in the language's standard library to perform memory management is a common paradigm. shared_ptr is not suitable for all object usage patterns, however.
The C programming language manages memory statically, automatically, or dynamically.Static-duration variables are allocated in main memory, usually along with the executable code of the program, and persist for the lifetime of the program; automatic-duration variables are allocated on the stack and come and go as functions are called and return.
Dangling pointers can appear in certain computer programming languages, e.g. C, C++ and assembly languages. A tombstone is a structure that acts as an intermediary between a pointer and its target, often heap-dynamic data in memory. The pointer – sometimes called the handle – points only at tombstones and never to its actual target.

A heap overflow, heap overrun, or heap smashing is a type of buffer overflow that occurs in the heap data area. Heap overflows are exploitable in a different manner to that of stack-based overflows. Memory on the heap is dynamically allocated at runtime and typically contains program data.
In computer science, heapsort is a comparison-based sorting algorithm which can be thought of as "an implementation of selection sort using the right data structure." [3] Like selection sort, heapsort divides its input into a sorted and an unsorted region, and it iteratively shrinks the unsorted region by extracting the largest element from it and inserting it into the sorted region.
Example of a binary max-heap with node keys being integers between 1 and 100. In computer science, a heap is a tree-based data structure that satisfies the heap property: In a max heap, for any given node C, if P is the parent node of C, then the key (the value) of P is greater than or equal to the key of C.
Shahmukhi (Shahmukhi: شاہ مُکھی, pronounced [ʃäː(ɦ)˦.mʊ.kʰiː], lit. ' from the Shah's or king's mouth ', Gurmukhi: ਸ਼ਾਹਮੁਖੀ) is the right-to-left abjad-based script developed from the Perso-Arabic alphabet used for the Punjabi language varieties, predominantly in Punjab, Pakistan.
