C Arrays
In this tutorial, you will learn to work with
arrays. You will learn to declare, initialize and access
elements of an array with the help of examples.
Arrays in C
An array is a variable that can store multiple values.
For example, if you want to store 100 integers, you can
create an array for it.
int data[100];
How to declare an array?
dataType arrayName[arraySize];
, For example,
1. float mark[5];
2. Here, we declared an array, mark, of floating-point
type. And its size is 5. Meaning, it can hold 5
floating-point values.
3. It's important to note that the size and type of an
array cannot be changed once it is declared.
Access Array Elements
You can access elements of an array by indices.
Suppose you declared an array mark as above. The
first element is mark[0], the second element
is mark[1] and so on.
Declare an Array
Few keynotes:
Arrays have 0 as the first index, not 1. In this
example, mark[0] is the first element.
