An array is a contiguous block of memory containing one or more elements of the same type and size. Each element in the array is accessed as a zero-based offset from the start of the array or by using the index [].
Examples:
int a[10]; // allocates memory for 10 integers (e.g., 40 bytes for a 4 byte int).
int x = a[5]; // accesses the 6th element (a[0] is the first element).
int *p = a; // point to start of the array.
p += 5; // advance pointer 5 * sizeof( int ) addresses.
*p = 10; // access the 6th element and assign the value 10.
int d * = new int[*p]; // dynamically allocate an array of 10 elements.
delete [] d; // release dynamic array.

∙ 12y agoAn array is a collection of one or more repeated instances of an object, referred to in a special way, that allows them all to have the same name, as a collection, but to be individually numbered. For instance, an array of 10 floating point numbers could be defined as ...
float array[10];
... and then used as array[0], array[1], array[2], ... array[8], array[9].
You can have multiple dimensions if you wish ...
float matrix[10][10];
... creates an array of 10 x 10. You would access it as matrix[0][0], through matrix[9][9]. Note carefully the syntax of sequential brackets, and don't be surprised that the multi-dimensioned array is actually an array of arrays. There is no limit, other than implementation and/or memory to the number of dimensions.

∙ 11y agoAn array is a static data container. It is used for storing data in a contiguous memory location. The individual array elements are indexed using the subscript. An array index always begins with 0.
Eg:
int arr[10]; //declaring an array - If the array is only declared, the size of the array should be mentioned within the square braces.
int arr[] = {1,2,3};//declaration and initialization - Here the size of the array is optional. If the size is not specified, then size equal to the number of elements specified inside the curly braces is allotted to the array.
Individual array elements can also be initialized/changed using the subscript operator
Eg:
arr[0] = 4;

How many dimensions can an array be created in c?
There is no language limit to "How many dimensions can an array be created in c?". The limit will depend on available memory.
What is the Maximum limit of array size in c language?
Platform-dependent.
How do you swap two adjecent no in array in c?
Option 1) Use a temporary variable: int x = array[i]; array[i] = array[i+1]; array[i+1] = x; Option 2) Use bit operators: array[i] ^= array[i+1] ^= array[i];
What is an ordered list of data structure using c plus plus?
An ordered list of data in any programming language is simply a sorted array or list. In C++ this can either mean a sorted array, vector, list or forward list.
What is the lowest subscript of an array in c plus plus?
The lowest subscript of an array in C, or C++ is 0.
How do you use in array?

How do you write a programme in c language using arrays to copy diagonal elements of a 2-d array into a 1-d array?
TO use a c language first step is to know about the c language and the steps to use the c progrmming language with the help of any elders or with the teachers. TO use the arrays you have to get th eknowledge of "c" language

How you create table in c language?
The simplest way to create a table in C is to use a two-dimensional array.
How many dimensions can an array be created in c?
There is no language limit to "How many dimensions can an array be created in c?". The limit will depend on available memory.
What is the Maximum limit of array size in c language?
Platform-dependent.
What is the difference between array in c and c sharp language?
The syntax to access a particular element in an array are the same in both languages: For example: assume array is an array of 10 int(egers): to get the first element: array[0] (both are 0 based indexing] int i = 0; while (i < array.Length) { // do something to array[i] } int i = 0; int length = sizeof(array) / sizeof(int); while (i < length) { // do something to array[i] } However, an array in C# is also enumerable (C does not have this feature) in C#, you may loop thru the array by: foreach (int number in array) { // do something to array[i] } Plus, C# is an Object-Oriented Language, so that an array may be of some object types, not just those primitiives data types in C: object[] objectArray; // any object derived from Object may be placed into objectArray, not just struct. In another variation, an array may be of Delegate type in C#(sort of like function pointers in C)
How do you swap two adjecent no in array in c?
Option 1) Use a temporary variable: int x = array[i]; array[i] = array[i+1]; array[i+1] = x; Option 2) Use bit operators: array[i] ^= array[i+1] ^= array[i];
What is meant by array with in structure in c language?
It means a structure has a member that is an array: typedef struct foo { int x[42]; // an array of 42 integers // other members... };
Why is c string defined as an array?
Every programming language treats strings as arrays. A C string is defined as being a null-terminated array of characters. A C string that does not have a null-terminator is just an array of character values, but without a null-terminator the onus is upon the programmer to keep track of the array's length.
How do you use an array to show the commutative property?
If the array consists of r rows and c column, and the total number of cells in the array are n = r*c, then r*c = n and c*r = n so that r*c = c*r : which is commutativity of multiplication.
Why you use array in c sharp programming?
Any feature in any computer language should be based on the need. In the last 2 years, I have not come across any need to use an array in my job. Yes, I do use collections, a lot of them, just never a fixed-size collection.
