Question

Changes in the economy have determined that for the EZ shipping company, a surcharge will be assessed on all packages that meet certain criteria. The surcharge is a function of the characteristics of the package and the zip code to which it is sent.

1. The regular charges for shipping are calculated as follows:
     For all weights five pounds and under, the shipping cost is $12.00.

     For weights over five pounds, the charge is calculated as follows:
                        If length * width * height + weight is:

greater than 5 and less than or equal to 15, the shipping cost is 14.00

greater than 15 and less than or equal to 34, the shipping cost is 17.00

greater than 34 and less than or equal to 45, the shipping cost is 21.00

greater than 45 and less than or equal to 60, the shipping cost is 33.00

greater than 60, the shipping cost is 105.00

2. The additional charges are calculated as follows:

            If the first digit of the zip code is a "4" then there is an additional surcharge of 5% on the shipping cost.

If the first digit of the zip code is a "6" then there is an additional surcharge of 9% on the shipping cost.

For all other zip codes there is an additional surcharge of 14% on the shipping cost.

3. Finally, if the zip code is even, then there is an additional surcharge of 2% of the shipping

            cost.

Write a program that allows the user to input (in this order) the zip code, weight, length, width and height of the package then prints out the following:

The zip code and dimensions of the package

The shipping cost

The surcharge

The total shipping cost (shipping cost plus surcharge(s))

I have written out the code and have been able to get it to run but when I added in the 2% for even numbers portion of my code every thing went weird with my outputs. Every thing still compiles and works but I am not recieving the outputs I desire. Any help remedying this would be greatly appreciated.

Answer 1

Explanation:

Syntax of IF condition

if(boolean) {

statements;

}

This will executes, entire block. If we have only one statement need of parenthesis( { } ) is optional.

if(boolean)

  statement;

But if you give semicolon after if condition, That will ends their only.

That is if(condition); if condition ends with semicolon. It does not contains any statement(s).

Infinity FOR loop: for(;;); is here.

if (zip % 2 == 0 );
surcharge2 = shippingCost*.02;

Replace your code AS:

if (zip % 2 == 0)
surcharge2 = shippingCost * .02;
else
surcharge2 = 0.d;

This code working fine. Thank Tou
