Write a program that asks for the weight of a package in pounds and then the distance the package is to be shipped [Input order: pounds distance]. With this information, calculate and display the shipping charges for that package. The two inputs and the output will be stored in a double array.
You may not assume that the values the user enters are valid. Because of this, your program will need to validate that the weight they enter is between 1 and 60, inclusive. The company can only ship packages between 1 pound and 60 pounds, inclusive (make sure that you allow for 1 and 60).
Once a valid weight has been obtained, your program will need to prompt the user for a valid distance until they enter a value greater than or equal to 1. The company has to ship a package at least 1 mile.
Output your results with two significant digits after the decimal place.
To calculate the shipping cost, figure the shipping rate based on the weight, then use the number of miles to calculate the actual shipping cost.
For example, for a package that weighs 22 pounds that is being shipped 297 miles, you should charge the individual $27.09 because: you should charge $9.03 (based on the weight) for the first 100 miles, $9.03 for the second 100 miles and another $9.03 for the remaining 97 miles, which is a fraction of 100 miles. Do not pro-rate the shipping charges based on partial mileage (like 97/100 miles).
Goals
Experience with creating and storing data in arrays.
Use looping structures to perform data validation on user input.
Testing your Program
Since there are so many ranges and boundaries in this program (ranges for weight and ranges for distance), you should test a number of different inputs in your program.
For instance, pick a distance of 57 miles and then test each of the following weights with it: 1, 10, 11, 20, 21, 30, 31, 40, 41, 50, 60. Then pick a particular weight such as 25 and then a few different distances: 1, 50, 100, 150, 200, 201, 576.
You should manually calculate the desired for each of those combinations and then see if your program generates the correct results.
Output Specifications
If your program does not follow the output structure shown below, it will not pass the test cases in Repl.it.
