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:apple:


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

            weight -= 1
        }
    }
}
else
    price = 2.00
That should work...just don't forget the semicolons!

Code:
float shippingCharge(float pounds, float ounces)
{
	float weight = pounds * 16 + ounces;
	
	// weight from 0 to 8 ounces
	if (weight <= 8.0)
		return 2.0;
	
	// weight from 8 to 32 ounces
	if (weight <= 32.0)
		return 2.0 + 0.75 * (weight - 8.0);
	
	// weight over 32 ounces
	return 20.0 + 1.15 * (weight - 32.0);
}

Good catch. I'd prefer
Code:
float weight = ceil(pounds * 16.0 + ounces);
though.
