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 array elements 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 array elements in descending order  */

#include <stdio.h>

int main()
{
    int arr[100];
    int size, i, j, temp;

    printf("Enter size of array :: ");
    scanf("%d", &size);

    printf("\nEnter elements in array::\n ");
    for(i=0; i<size; i++)
    {
        printf("\nEnter %d element in an array :: ",i+1);
        scanf("%d", &arr[i]);
    }

    for(i=0; i<size; i++)
    {
        for(j=i+1; j<size; j++)
        {
            if(arr[i] < arr[j])
            {
                temp = arr[i];
                arr[i] = arr[j];
                arr[j] = temp;
            }
        }
    }

    printf("\nElements of array in sorted descending order :: ");
    for(i=0; i<size; i++)
    {
        printf(" %d ", arr[i]);
    }

    return 0;
}

OUTPUT : :

/*  C program to sort array elements in descending order  */

Enter size of array :: 7

Enter elements in array::

Enter 1 element in an array :: 5

Enter 2 element in an array :: 2

Enter 3 element in an array :: 7

Enter 4 element in an array :: 9

Enter 5 element in an array :: 1

Enter 6 element in an array :: 0

Enter 7 element in an array :: 8

Elements of array in sorted descending order ::  9  8  7  5  2  1  0
