How do you represent a one dimensional array in memory?
A one-dimensional array is always represented as a single contiguous block of memory. The size of the allocation is determined by the array's type and the number of elements of that type. For instance, if you create an array of 10 elements where each element is 4 bytes in length, the total allocation will be 40 bytes. The array name is a reference to the start of the allocation and individual elements are accessed via an indexed offset from this reference, such that the first element is at offset 0, the next is at offset 1, and so on.
What is contiguous storage allocation?
Contiguous means to share an edge or boundary, touching, adjacent, neighbouring and so on. Thus contiguous storage allocation is any allocation that consumes two or more contiguous storage elements. In the case of contiguous memory allocation, this means two or more contiguous memory addresses are allocated. A one-dimensional array is an example of a contiguous memory allocation, where one array element (a data type) is immediately followed by the next.
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.
Declaration of two dimentional array in functions?
Possible. void foo (void) { int array [10][20]; ... }

Create an anonymous array in java?
An anonymous array in Java is just an array with its contents declared at instantiation. Normal array declaration: int[] nums = new int[3]; nums[0] = 0; nums[1] = 1; nums[2] = 2; Anonymous array declaration: int[] nums = new int[] {0,1,2}; The two examples above will each result in the same array.
How you can initialize an array with data values during declaration?
int myArray[] = {1,2,3,4,5};
Can a linked list implemented using an array be accessed by giving the location?
A linked list implemented with an array defeats the purpose of using a linked list, which is to address the memory allocation problems associated with arrays.
What is array in structures?
array is used to store the ame datatypes syntex: int array[]=new int[size]; dynamic declaration of array insertion array[1]=20; 2nd way: int array[]={10,20,30}; *important:- int array[20]={20,30,49,....} this way is wrong in java as this is static way and in java all is done dynamically
What is the difference between sequential allocation and linked allocation in java?
Sequential allocation refers specifically to arrays. An array is, by definition, a contiguous block of memory. The index of the array is used as an offset from the memory address of the beginning of the array - this is why access to any element in an array takes a constant amount of time to compute. "Linked allocation" is best described by linked lists. These data structures are connected by a series of nodes. A node contains at least two pieces of information: some piece of data and a reference (link) to the next node in the chain. Since changing the position of a node in a linked list only requires changing references to other nodes, insertion and deletion is trivial. Note that these "referential" linked data structures are not the only way to link data, just the easiest to understand and implement.
