An array in C language is a data structure used to store multiple elements of the same data type. It consists of contiguous blocks of memory, with each element accessed via an index. Advantages of arrays include convenience in storing and processing data of the same type, efficient element access, and ease of looping and iteration. When declaring an array, you specify the data type and size, and index from 0 to the array size minus one. Access array elements using indexes, but be aware that the array size cannot be changed and the index must be within the range, otherwise an array out-of-bounds error may occur.
What is an array in C language?
An array is a data structure used to store multiple elements of the same data type. It is a continuous block of memory, and each element occupies a fixed memory space. Each element can be accessed by its index, which starts at 0 and ends at the array size minus one.
Advantages of arrays:
Declaring arrays:
To declare an array, you need Specify the data type of the array and the size of the array. The following is an example of declaring an array of integers:
<code class="c">int myArray[5];</code>
This will create an array containing 5 integer elements, indexed from 0 to 4.
Accessing array elements:
Array elements can be accessed by index just like ordinary variables. For example, to access the first element in the array myArray
, you would use:
<code class="c">myArray[0]</code>
