What is Array in C? Write a program to sort numbers in descending order.

 

• An array is a collection of data items, all of the same type, accessed using a common name.
• A one-dimensional array is like a list;  A two dimensional array is like a table;  The C language places no limits on the number of dimensions in an array, though specific implementations may.

1.     #include <stdio.h>

2.     void main ()

3.     {

5.         int number[30];

7.         int i, j, a, n;

8.         printf("Enter the value of N\n");

9.         scanf("%d", &n);

11.         printf("Enter the numbers \n");

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

13. 	        scanf("%d", &number[i]);

15.         /*  sorting begins ... */

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

18.         {

19.             for (j = i + 1; j < n; ++j) 

20.             {

21.                 if (number[i] < number[j]) 

22.                 {

23.                     a = number[i];

24.                     number[i] = number[j];

25.                     number[j] = a;

26.                 }

27.             }

28.         }
