If you want to make your career in the field of programming, then the first thing you have to learn is the basics of arrays. After that only, you could do the array problem solving questions.

Let us know what an array is.

An array is the collection of elements of the same data type stored at contiguous memory locations

What are the uses of an Array?

An array is a collection of elements of the same data type and its size sequence is fixed.

An array is a derived data type. When we want to store a large amount of data , or access or manipulate a large amount of data, then we use arrays.

In an Array all elements have the common name.

Arrays work on index numbers. The index of an array starts from 0 and ends with size-1. The collection of the same data type where each element has a separate memory location. An array is static and is a part of linear data structure.

What are the characteristics of an array? 

Have a look at some of the main characteristics of an array?

All the elements of an array have the same name and they are separated from one another by an index number.

We can modify the elements of an array separately without affecting other elements.

Index numbers have a very crucial role when we call an element.

The elements of an array are stored in contiguous memory locations.

The size of an array depends on the type of array and numbers of elements.

Types of Array.

There are basically two types of array.

1.     Single dimensional array

2.     Multi dimensional array

What is a single dimensional array?

Single dimensional array is an array that is defined with only one index.

Single dimensional array is used for searching and sorting.

Syntax:

Data type Array name [size];

     Example……

int ar [20];

 What is multi dimensional array?

 Multi dimensional array is that which works with a double index. It is used for matrix manuculation.

 Syntax….

Data type Array name[size][size];

  Example…..                

                            Int ar[30][10];

 Write a program to find a sum of five nos. using Array in C language.

 #include<stdio.h>

#include<conio.h>

void main()

{

int a[5]={18,10,17,34,21};

int i,s=0;

clrscr();

printf("Entered elements of arrays =");

for(i=0;i<5;i++)

{

printf("\n%d",a[i]);

s=s+a[i];

}

printf("\nSum=%d",s);

getch();

}

 OUTPUT

 Enter the elements of arrays =

18

10

17

34

21

Sum = 100
