OUTPUT:

Enter the length of array (length must be less than or equal to 10) : 5

Enter the value of element no 1 : 1

Enter the value of element no 2 : 2

Enter the value of element no 3 : 3

Enter the value of element no 4 : 4

Enter the value of element no 5 : 5

Value of element no 1 is 5

Value of element no 2 is 4

Value of element no 3 is 3

Value of element no 4 is 2

Value of element no 5 is 1
