1. Use nested if multiple selection structure to write a program that determine the shipping cost passed on a distance as given in the following table. the program will assign a value to a cost variable passed on an integer distance value entered by the user.
2. Rewrite the same program using a switch multiple selection structure.(hint: normalize the distance )

Distance	Cost
0 through 99	5.00
More than or equal 100 but not more than 499	8.00
More than or equal 500 but less than 999	10.00
1,000 or more	12.00
