Areas of Rectangles.

The area of a rectangle is the rectangles length times its width. Write a program that asks for the length and width of two rectangles. The program should tell the user which rectangle has the greater area, or if the areas are the same. It should also tell if any of the inputs are invalid (i.e. negative). Show output tests for all three conditions.

Sum of Numbers .

Hand in your code and 2 runs (testing a positive and a negative number entered).

Write a program that asks the user for a positive value. The program should use a loop to get the sum of all the integers from 1 up to the number entered.

For example, if the user enters 50, the loop will find the sum of 1, 2, 3, 4, 50.

Input validation: Do not accept a negative number.
