the problem is the nuggets come in packs of 6 9 and 20 and i have to make a program that outputs the different pack combinations that the user can buy for an order. for example,

if the user wanted 54 nuggets, they could have nine packs of six or five packs of nine.

ok let's start with basics: #include <iostream> using namespace std; int main() { int amt; cout << "How many nuggets would you like to purchase?" << endl; cin >> amt; ...... hmm now

oh btw the user has to buy something that's a multiple of these. I mean what if he buys less than 6, or what if he buys 7, or 8, etc.

jaskaranBest ResponseYou've already chosen the best response.0
then it cannot be bought

bahrom7893Best ResponseYou've already chosen the best response.0
So i guess we could add the following: do { cout << "Please choose a different number: " cin >> ant; } while (a%6!=0  a%9!=0  a%20!=0 );

#include <iostream> #include <iomanip> using namespace std; void main() { int p6, p9, p20, order; cout<<"How many nuggets would you like to order?"; cin>>order; p20=order/20; cout<<p20<<" 20 piece package."<<endl; } kay there. so that works for if i input 20. lol.

at least 6 9 and 20 multiples can be done with, for example, an if (order%6==0) p6=order/6; cout<<p6 "6piece packages."<<endl; etc

in fact this program can be generalized too, just take input three packet sizes from user and replace them with 6, 9, 20 and there you have it.

jesssicaBest ResponseYou've already chosen the best response.0
so ask the user to guess first?

This problem (albeit in python) is on one of the problem sets for course 6.00, problem set 2 to be precise. So you might want to ask there. I've done it, and could give you my code, but it's really basically the same as jaskaran's.
 2 years ago

thinkpad20Best ResponseYou've already chosen the best response.0
the reason you divide by the variable is because, for example, if you have a box of nuggets with 20 pieces, you know that the maximum number of boxes you could have (and thus the maximum you need to test) is your target/20. As for the +1, it's because the python range function gives you numbers until one behind the number you input, e.g.: range (0,5) 0, 1, 2, 3, 4 C++ may or may not be similar.

does python solve for a b and c in that equation num==2*a + 9*b + 20*c ? cause i dont think c++ does .

okay i am trying to understand jaskarans program...if the input was 6, then how would it print b and c as 0 if they were initialized as 1 ?
 2 years ago

thinkpad20Best ResponseYou've already chosen the best response.0
I think the reason he put in the line a=b=c=1 is just to initialize them as numbers. But actually I don't think it really matters, since either way you're simply looking at a, b and c values iterated between 0 and number/(size of nugget box). I'll paste my code for it, as upon second look mine is a little different (I don't use a while loop for example) and a bit simpler, and also mine has annotations that might make it more easy to understand. Anyway, here's mine: http://pastebin.com/dpJuFujR Actually I disagree with jaskarans' use of the while loop because, upon a cursory glance, it seems to be irrelevant: the value starts as true, the for statements run, and then the value is false. The program would run just as well without any while statement. As for what you asked, no, python doesn't actually solve (algebraically) the equation as you said. I'm sure you can write a program that solves algebraic equations, but the much more simple answer when dealing with a program language is to use what a computer is good at: trying out a bunch of stuff at blazing speed and testing if it's the right answer.

thinkpad20Best ResponseYou've already chosen the best response.0
As a matter of fact, looking back at my program now, the S=0 M=0 L=0 statements I made at the beginning are also irrelevant. S, M, and L values are chosen by the for function, so even if I had not mentioned them at all in the beginning it still wouldn't matter.

i guess python and c++ work differently because i tried translating yours and it is giving me a neverending loop. i am not sure c++ is capable of checking the range by itself.. idk. thanks though !

This is naturally a recursive problem, and since it's a Sunday evening and I'm bored, I wrote this little hack that solves your problem: http://ideone.com/2iYBp

thinkpad20Best ResponseYou've already chosen the best response.0
jesssica  there shouldn't be any possibility of an infinite loop occurring with only for statements; they have a strict beginning and end. Or at least, Python is that way and I would assume C++ is as well. Are you sure you're not using a while statement or other loopgenerating code?

thanks everyone, i ended up using mod and an else of subtracting from the initial and remainders.
