What is Array in C Language

one-dimensional Array in c

Array Definition: Array is a collection of data of the same type. It can be used to store groups of data simultaneously.

An array can store data of the same data type means an integer array can store only integer values, a character array can store only character values, and so on.

We can not fetch knowledge from an array directly thus we tend to use index purposes.

The array could be an assortment of comparable parts styles with a contiguous memory location. Learn C Language

The array is an Associate in Nursing object that contains components of an identical information kind. it's an information structure wherever we have a tendency to store similar elements. 

we will store solely a hard and fast set of components during an array. The array is index-based, the primary component of the array holds on at the zero indexes.

Types of Array in C 

There are two types of Array.

1. Single-Dimensional Array

2.Multidimensional Array

Advantages of Array in C

Code Optimization: Array makes the code optimized, we can retrieve or sort data efficiently.

Random access: we can get any knowledge placed at an index position.

Disadvantages of Array in C

Size Limit: An array can store only the fixed size of elements in the array.

Array in c programming syntax

int a[]=new int[5];

Here is the name of the array.

int is the data type of array.

The size of the array is five suggests that we can store most five values during this array.

How To Initialization of array in C?

Two-dimensional array in data structure

Array: Array is a collection of data of the same data type. It can be used to store groups of data simultaneously.

The array can store data of the same data type means an integer array can store only integer value character array can store only character value and so on.

We can not fetch data from the array directly therefore we use an index point.

The array is a collection of similar types of elements that have a contiguous memory location.

An array is an object which contains elements of a similar data type. It is a data structure where we store similar elements. Earn Money

We can store only a fixed set of elements in an array.

The array is index-based, the first element of the array is stored at the 0 indexes.

2-dimensional syntax

int a[][]=new int[3][3];

Here is the name of the array.

int is the data type of array.

The size of the array is 3x3 means we can store a maximum of 9 values in this array.
