macOS c++ question

how would I go about creating a program to calculate shipping charges?


i.e. If the order weight is less than 8 ounces, there is a flat rate charge of $2.00.
If the order weight is between 8 ounces and 32 ounces, the charge is $2.00
plus $0.75 for each ounce, or part thereof, over 8 ounces.
If the order weight is greater than 32 ounces, the charge is $20.00 plus
$1.15 for each ounce over 32 ounces.


I would now how to the only problem is it excepts pounds and ounces

so someone can put in 0.5 pounds and it should be 2.00 also

1) make sure whatever the value is it is in ounces
2)
---if (weight > 8)
---{
---------if (weight > 32)
---------{
--------------price = 20.00
--------------weight -= 32
--------------while (weigh != 0)
--------------{
------------------price += 1.15
------------------weight -= 1
---------------}
---------}
---------else
---------{
-------------price = 2.00
-------------weight -= 8
-------------while (weight != 0)
-------------{
------------------price += .75
------------------weight -= 1
-------------}
--------}
--}
--else
------price = 2.00


hope this design helps


EDIT: WHY DOESNT THE SPACES EVER SHOW UP!!!

hankolerd, you could use the code tags to preserve formatting.

Code:

if (weight > 8)
{
    if (weight > 32)
    {  
        price = 20.00
        weight -= 32
        while (weigh != 0)
        {
            price += 1.15
            weight -= 1
        }    
    }   
    else
    {   
        price = 2.00
        weight -= 8
        while (weight != 0) 
        {
            price += .75
            weight -= 1
        }
    }
}
else
    price = 2.00

That should work...just don't forget the semicolons!

Based on this requirement:

plus $0.75 for each ounce, or part thereof,

Shouldn't this be considered:

Code:

float shippingCharge(float pounds, float ounces)
{
	float weight = pounds * 16 + ounces;
	[color=red]if ((int) weight < weight) { weight = (int) (weight+1) } ; [/color]
     ...
}

Good catch. I'd prefer though.

Code:

float weight = ceil(pounds * 16.0 + ounces);

Yep. that's better.
