What is the term given to the memory allocation that takes place during run time rendering the resizing of an Array?

A reallocation. Note that whenever we reallocate an array, we increase the size of the current allocation if there is sufficient free memory beyond the current allocation or we allocate entirely new memory if there isn't. But when we reduce the size of an array, we simply release the redundant memory at the end of the array; we never allocate new memory. However, because the amount of memory being allocated has to either increase or reduce in size, both are termed a reallocation.

What is the use of Constructor with Dynamic allocation?
Constructors are necessary to initialize classes. It allows to avoid to a lot of problems with unauthorized access of memory. Dynamic allocation makes possible allocation of memory during execution of program. If you do not use dynamic allocation, all required memory will be allocated during initialization phase (constructors are usually responsible for that). But you can't use more memory. Dynamic allocation was designed to overcome such problems.
What are types of memory allocation?
There are two types of memory allocations. 1. Static memory allocation 2. Dynamic memory allocation
What Linked list uses.type of memory allocation?
Linked lists use dynamic memory allocation (also called "heap memory allocation", as the linked list is stored in heap memory).

Is an operating system responsible for managing processor time and memory allocation?
The processor time is a function of the processor. The memory allocation is a function of the operating system.
Difference between contiguous and non contiguous memory allocation?
In a contiguous memory allocation there is no overhead during execution of a program. In a non contiguous memory allocation address translation is performed during execution.

What do you mean by run time memory allocation?
When the allocation of memory to the program is done on need, during the execution of a program, it is called as the dynamic memory allocation. Memory is allocated from a free memory pool called as heap.The only way to access this dynamically allocated memory is through pointers. Dynamically allocated memory can be freed at run time and again added to heap.
What is meant by contiguous memory allocation in C?
Contiguous memory allocation in C programming refers to the assigning of consecutive memory blocks to a process. Contiguous memory allocation is one of the oldest and most popular memory allocation schemes in programming.
What is the difference between contiguous and non contiguous memory allocation?
in contiguous allocation overhead during execution of a program.in non contiguous allocation address translation is performed during execution of a program..
Compare and contrast dynamic memory allocation and the allocation of files in secondary storage?
Static Memory Allocation: Allocating the total memory requirements that a data structure might need all at once without regard for the actual amount needed at execution time. Dynamic Memory Allocation: The opposite strategy of static memory allocation - Dynamic Memory Allocation, involves allocating memory as-needed.
What Linked list uses.type of memory allocation?
Linked lists use dynamic memory allocation (also called "heap memory allocation", as the linked list is stored in heap memory).
Difference between contiguous and non contiguous memory?
In contiguous allocation there is no overhead during execution of a program. In noncontiguous allocation address translation is performed during execution Contiguous memory allocates single area of memory Noncontigious memory allocates several memory areas - one memory are to each component of a process
What is contiguous memory allocation in os?
Memory allocation: When a program asks for memory and gets it. Contiguous allocation: When the memory is in one big block, for example memory addresses 1000-2000, as opposed to "fragmented allocation" where the memory comes as several smaller blocks in different places, for example memory addresses 1000-1050, 2050-2125, ...
How do you display matrix in c using dynamic memory allocation?
