$//$ This program demonstrates the use of pointer variables

$//$ It finds the area of a rectangle given length and width

$//$ It prints the length and width in ascending order

Exercise $1$: Complete this program by filling in the code $($places in bold$).$ Note:

use only pointer variables when instructed to by the comments in bold.

This program is to test your knowledge of pointer variables and the & and

$*$ symbols.

Exercise $2$: Run the program with the following data: $1015.$ Record the output
