Output and Control
I've been working on a problem that it just boggling my mind. I need to be able to convert a given number into change (i.e. quarters, dimes, nickels, pennies.) so if i type in 3.50 i get 14 quarters, if i type in 3.45 i get 13 quarters and two dimes etc. what i have so far is each number individually (i.e 3.50 gets me 14 quarters, 35 dimes, 70 nickels, 350 pennies) the question i have is, how am i able to do this? this is what i have so far

Code:

``` #include <iostream> #include <iomanip> using namespace std; int main( ) {         float amount;         float quarters;         float dimes;         float nickels;         float pennies;                 cout << "I will convert your money into change. \n\n";         cout << "Enter the amount:";         cin >> amount;         quarters = amount/.25f;         cout << "You recieve " << quarters << "Quarters.\n\n" ;         dimes = amount/.10f;         cout << "You recieve " << dimes << " Dimes.\n\n" ;         nickels = amount/.05f;         cout << "You recieve " << nickels << " Nickels.\n\n" ;         pennies = amount/.01f;         cout << "You recieve " << pennies << " Pennies.\n\n" ;                 return 0; }```
this code does each coinage individually, but i need them to be unified
ive tried many different things so far, to no avail.

You must update your total amount after each conversion:
Code:

```quarters = amount / .25f; amount -= quarters * .25f; dimes = amount / .10f; amount -= dimes * .1f;```
etc...

another problem... i guess it automatically rounds up? so u end up with 0 after u subtract teh quarters

ooh i got it

Code:

``` quarters = amount/.25f;         amount  -= quarters *.25f;         cout << "You recieve " << quarters << " Quarters.\n\n" ;                 dimes = amount/.10f;         cout << "You recieve " << dimes << " Dimes.\n\n" ;         amount  -= dimes *.10f;                 nickels = amount/.05f;         cout << "You recieve " << nickels << " Nickels.\n\n" ;         amount  -= nickels *.05f;                 pennies = amount/.01f;         amount  -= pennies *.01f;         cout << "You recieve " << pennies << " Pennies.\n\n" ;```
also note that i changed the type of variable from float to int, seeing as there is no such thing as half a quarter/dime/nickel/penny :p
