Calculation Troubles
I have to take a 4-digit number and calculate it like this:
First 70 cubic meters $5.00 minimum cost
Next 100 cubic meters 5.0 cents per cubic meter
Next 230 cubic meters 2.5 cents per cubic meter
Above 400 cubic meters 1.5 cents per cubic meter
Soo, for the number 203, it would calculate $10.83. Ok, I've set it up numerous ways, and can't get anywhere near the correct price.Basically what I need to know is -- How can I break up one number into those 4 different calculations?
Ever heard of ifs? Sounds like they'd come in handy here.
FAQ
"The computer programmer is a creator of universes for which he alone is responsible. Universes of virtually unlimited complexity can be created in the form of computer programs." -- Joseph Weizenbaum.
"If you cannot grok the overall structure of a program while taking a shower, you are not ready to code it." -- Richard Pattis.
Loops would be another option. But you need to show us what you got before we can go into any more detail
I'll attach what I've already got. Keep in mind I'm very new to this, hehehe. Thanks for the help so far.
I tried doing this for the calculations, but my numbers are still off by a few dollars.
cost1 = gasused%10 * 5.00;
cost2 = (gasused/10)%10 * 0.05;
cost3 = (gasused/10/10)%10 * 0.025;
cost4 = (gasused/10/10/10)%10 * 0.015;
totalcharges = cost1 + cost2 + cost3 + cost4;
This was fun:
PHP Code:#include <iostream.h>
#include <windows.h>
#include <stdio.h>
/* RULES:

*/
int main()
{
int number;
float total = 5.0f;
float price;
printf("Enter cubic meters:\n");
cin >> number;
if( number <= 70 ) {
printf("Total price: $%f.\n", total);
return 0;
} else if( number <= 170 )
price = 0.05f;
else if( number < 400 )
price = 0.025f;
else if( number > 400 )
price = 0.015f;
total += price * number;
printf("The total price is: $%f.", total );
return 0;
}

(it should be realized my posts are all in a light hearted manner. And should not be taken offense to.)
I'm glad you thought it was fun.Thanks for the help!
