How to represent arrays in c++

An array in C is a data structure used to store a group of contiguous memory cells of the same data type. Elements of an array are accessed using the subscript operator, with subscripts starting from 0. The properties of an array include size (the number of elements stored), data type (the data type of the elements), and address (the memory address of the first element of the array).

Representation of array in C

Definition:
Array is a storage with A contiguous group of memory cells of the same data type.

Representation:
The following syntax is used to represent arrays in C:

<code class="cpp">数据类型 数组名[数组大小];</code>

For example:

<code class="cpp">int myArray[5];</code>

This declaration creates an array of size 5 An array of integers named myArray.

Memory layout:
Array elements are stored in contiguous memory units, and the size of each element is determined by the data type. The first element of the array starts at memory address 0, and the address of the last element is equal to (array size - 1) * (element size).

Access elements:
You can use the subscript operator to access array elements:

<code class="cpp">myArray[索引值]</code>

The index value is an integer, starting from 0, indicating the array to be accessed element.

Array properties:

• Size: The size of the array, that is, the number of elements stored.
• Data type: The data type of the elements in the array.
• Address: The memory address of the first element of the array.

Note:

• The size of the array is determined when it is declared and cannot be changed dynamically.
• Array elements are initialized to 0 or NULL by default.
• Arrays can be multi-dimensional, such as two-dimensional arrays or three-dimensional arrays.
