What is an Array ?

Arrays a kind of data structure that can store a fixed-size sequential collection of elements of the same type. An array is used to store a collection of data, but it is often more useful to think of an array as a collection of variables of the same type.

 
 

Instead of declaring individual variables, such as number0, number1, …, and number99, you declare one array variable such as numbers and use numbers[0], numbers[1], and …, numbers[99] to represent individual variables. A specific element in an array is accessed by an index.

All arrays consist of contiguous memory locations. The lowest address corresponds to the first element and the highest address to the last element.

Here is source code of the C++ Program to Sort the elements in array in descending order. The C++ program is successfully compiled and run(on Codeblocks) on a Windows system. The program output is also shown in below.

 

SOURCE CODE : :

/* C++ Program to Sort the elements in array in descending order */

#include<iostream>

using namespace std;

int main()
{
    int i,j,a[50],size,temp;
    cout<<"Enter array size( Max:50 ) :: ";
    cin>>size;
        cout<<"\nEnter array elements :: \n";

        for(i=0; i<size; i++)
        {
            cout<<"\nEnter arr["<<i<<"] Element :: ";
                cin>>a[i];
        }

    cout<<"\nData before sorting :: \n\n";

    for(i=0;i<size;i++)
    {
      cout<<" "<<a[i]<<" ";
    }

    for(i=0;i<size;i++)
    {
    for(j=0;j<size-i-1;j++)
    {
    if(a[j]>a[j+1])
    {
    temp=a[j];
    a[j]=a[j+1];
    a[j+1]=temp;
    }
    }
    }
    cout<<"\n\nData after sorting :: \n\n";
    for(j=size-1;j>=0 ;j--)
    {
    cout<<" "<<a[j]<<" ";
    }
    cout<<"\n\n";
    return 0;
}

OUTPUT : :

/* C++ Program to Sort the elements in array in descending order */

Enter array size( Max:50 ) :: 8

Enter array elements ::

Enter arr[0] Element :: 4

Enter arr[1] Element :: 1

Enter arr[2] Element :: 3

Enter arr[3] Element :: 2

Enter arr[4] Element :: 6

Enter arr[5] Element :: 7

Enter arr[6] Element :: 9

Enter arr[7] Element :: 0

Data before sorting ::

 4  1  3  2  6  7  9  0

Data after sorting ::

 9  7  6  4  3  2  1  0


Process returned 0

Above is the source code for C++ Program to Find Duplicate Elements in an Array which is successfully compiled and run on Windows System.The Output of the program is shown above .
