What is array meaning in C language

In C language, an array is a data structure that stores data of the same type in sequence in continuous memory, accessing elements from 0 through integer indexes. Its features include: storing the same type of data, sorting elements in order, accessing elements through indexes

The meaning of array in C language

An array, i.e. an array, is a data structure that stores data elements of the same type in sequence in continuous memory space. Array elements can be accessed through an index, an integer starting from 0, which indicates the position of the element in the array.

Features of arrays:

• Store data elements of the same type
• Elements are arranged in order
• Access elements through index

Declaration and initialization of arrays:

Arrays are declared in C using the following syntax:

类型数组名[大小];

in:

• Type : Data type of the element in the array
• Array name : The name of the array
• Size : Number of elements in an array

The array can be initialized with the following syntax:

类型数组名[] = {元素1, 元素2, ..., 元素n};

in:

• Type : Data type of the element in the array
• Array name : The name of the array
• Element 1, Element 2, ..., Element n : Elements in an array

Use of arrays:

To access elements in an array, you can use the following syntax:

数组名[索引]

in:

• Array name : The name of the array
• Index : The position of the element in the array (starting from 0)

Example:

The following example declares an array of integers named numbers and initializes them to 5 elements:

 <code class="c">int numbers[] = {1, 2, 3, 4, 5};</code>

To access the third element in the array, you can use the following code:

 <code class="c">int third_element = numbers[2];</code>
