ARRAY

ARRAY

• Array is group of element with same datatype
• It helps to develop efficient program. 
• It provides the ability to use a single name to represent a collection of items.

USE:

• store data of same datatype 

TYPE OF ARRAY
1. ONE DIMENSION ARRAY

Syntax:
              data_type array_name [size];

2.MULTI DIMENSION ARRAY

Syntax:
              data_type array_name [a1][a2]……….. [an];
Where an is the size of the [i]th dimensions.

Let's understand with example

SORTING OF ARRAY

#include<iostream>

 using namespace std;

int main()

{

    cout << "Write a Program in C++ to short integer array.\n\n\n";

            int a[50] , n , i , j , temp;

            cout << "Enter the size of array: ";

            cin >> n;

            cout << "Enter the array elements: ";

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

                        cin >> a[i];

            for (i=1 ; i < n ; ++i)

            {

                        for (j=0 ; j < (n-i) ; ++j )

                                    if ( a[j]  > a[j+1] )

                                    {

                                                temp = a[j];

                                                a[j] = a[j+1];

                                                a[j+1] = temp;

                                    }

            }

            cout << "Array after bubble sort:";

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

                        cout << " " << a[i];

return 0;

}
