Stuck on calculations part

[mim97]

Question: Write a C++ program that inputs the amount of money, calculate how many toy eggs you can buy and calculate the remaining coupons.

One egg toy = 1 Dirham
One egg toy = 1 coupon.
Five coupons = 1 Free egg toy.
For example, if you have 12 Dirhams you get 12 egg toys and 12 coupons, using the 12 coupons you can get 2 more egg toys so total will be 14 egg toys
and 2 remaining coupons.

Algorithm:
1. Prompt the user to enter the amount of money.
2. Calculate how many egg toys you can buy with money entered.
3. Calculate the remaining coupons.
4. Print the amount of egg toys you will get and the remaining coupons.


#include<iostream>
using namespace std;
int main()
{
int dirhams, toyeggs, coupons, remainingcoupons;

cout<<" Enter the amount of money: "
cin>>dirhams;


//i know i should use if else statements but i dont know how to write the formulas




cout<<" You got " <<toyeggs<< " and "<<remainingcoupons<<" remaining coupons"
return 0;
}

off the top of my head, there is probably a basic way to do it with logs without brute force, but if you just divide by 5 in a loop until you get a number less than 1, add that up, and you will get the answer with brute force.

So for every egg toy you buy you get a coupon?

If so then once you have the int dirhams then make
dirhams = eggs
eggs = coupons
coupons divided by 5 = eggsC
(this will give you the remainder or you can manipulate it to get a float that youll have to declare.

eggsC + eggs = outputEggs


cout<<" You got " <<outputEggs << " and "<< yourdeclaredvariable<<" remaining coupons"
return 0;

[jonnin]

it can nest though, as I read it? if he has 100 money, then he can get 100 coupons and 20 more eggs that give 20 coupons that give 4 more eggs...

there probably is a direct computation. its the sum of money + money/5 + previous/5 + previous/5 ….

i wrote this, and is still get the wrong result

#include<iostream>
using namespace std;
int main()
{
int dirhams, toyeggs, coupons, remainingcoupons, eggs;

cout<<" Enter the amount of money: ";
cin>>dirhams;
dirhams = eggs;
eggs = coupons;
remainingcoupons = coupons / 5.0;
toyeggs = remainingcoupons + eggs;




cout<<" You got " <<toyeggs<< " and "<<remainingcoupons<<" remaining coupons";
return 0;
}

That's close. Just remember that assignment goes from right to left, so

dirhams = eggs;
eggs = coupons;

should be

eggs = dirhams;
coupons = eggs;

Also you're using remainingcoupons to represent two things: the eggs from coupons and the number of coupons that remain when you're done. I'd use two variables to make it clear:

#include<iostream>
using namespace std;
int
main()
{
    int dirhams, coupons, remainingcoupons;
    int eggsFromDirhams, eggsFromCoupons;

    cout << " Enter the amount of money: ";
    cin >> dirhams;
    eggsFromDirhams = dirhams;
    coupons = eggsFromDirhams;
    eggsFromCoupons = coupons / 5;
    remainingcoupons = coupons % 5;

    cout << " You got " << eggsFromCoupons + eggsFromDirhams
	 << " eggs and " << remainingcoupons << " remaining coupons\n";
    return 0;
}

[jonnin]

so is 100 money 120 or 124 eggs?

Thankyou guys so much @dhayden and @jonnin , i get it now, much much appreciated.
