What are types of memory allocation?
There are two types of memory allocations. 1. Static memory allocation 2. Dynamic memory allocation
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 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).
Advantages of dynamic memory allocation in data structure?
The main advantage of dynamic memory allocation is flexibility: the sizes of structures (or upper bounds on the sizes) do not need to be known in advance, so any size input that does not exceed available memory is easily handled. There are costs, however. Repeated calls to allocate and de-allocate memory place considerable strain on the operating system and can result in "thrashing" and decreased performance. In addition, one has to be very careful to "clean up" and de-allocate any memory that is allocated dynamically, to avoid memory leaks. The general rule of thumb is, if you can allocate memory statically, do it, because the result will probably be faster code that is easier to debug. But if you need to handle wide-ranging input sizes, then dynamic memory allocation is the way to do it.
A C program using dynamic memory allocation to sort n names in ascending order?
Writing a C program that uses dynamic memory allocation to sort names in ascending order is a typical computer science assignment. To write this program, you must be in UNIX.
What are types of memory allocation?
There are two types of memory allocations. 1. Static memory allocation 2. Dynamic memory allocation
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.
How do you display matrix in c using dynamic memory allocation?
Memory allocation is not necessary to display a matrix.

What is the special features of pointers in c?
Dynamic memory allocation
At what time the memory is allocated for variable in c and c?
Static memory allocation occurs at compile time where as dynamic memory allocation occurs at run time.
What are the different function used for dynamic memory allocation?
alloc :- to allocate memory. calloc :- to free the memory.
What is difference in static and dynamic storage allocation?
Static storage allocation is when a program dedicates an amount of memory for its use at the start of the program. Dynamic storage allocation is when a program only takes storage as it needs it.
What are the recent memory management schemes?
Single-user contiguous Fixed Partitions Dynamic Partitions Relocatable Dynamic Partitions Paged Memory Allocation Demand Paging Working Set Segmented Memory Allocation Segmented/Demand Page Memory Allocation -------Taken from "Understanding Operating Systems. 6th edition pg 99
What is segmented page allocation?
Segmented page allocation is a type of memory management that uses base and bound registers to determine memory faults, similar to dynamic page allocation. More importantly it is different to dynamic page allocation since the entire process doesn't have to be in memory, similar to using virtual memory paging where the program is broken into pieces. Unlike virtual memory paging, the maximum virtual memory size is limited to the size of physical memory.
What is the maximum size of memory available for dynamic memory allocation?
The maximum memory that can be dynamically allocated depends on the size of the heap memory. Dynamic blocks of memory can be allocated in system heap until it is not full.
