I need help with C++

MegaloJntariac · Oct 20, 2009

Here is where I am at now. I can get it to execute, but its:

- Not taking the fee out and posting it

- Its only changing bills but not with the coins, and if i input just a decimal it shows the coins, so i need it to do both.

Win32 Console file

Code:

#include &lt;iostream&gt;
#include &lt;iomanip&gt;
#include &lt;cmath&gt;
using namespace std;

void change(double, int&amp;, int&amp;, int&amp;, int&amp;, int&amp;, int&amp;);
void change(double, int&amp;, int&amp;, int&amp;, int&amp;);  




bool validFee(double a)
{
return (a &lt;= 1000);
} // end Bool
void main()
{
int quar=0, dime=0, nick=0, penn=0, hunds = 0, fifts= 0, twents = 0, tens = 0, fives = 0, ones = 0;
double a;    //price of check &lt; $1000.01

do
{
cout&lt;&lt;"Enter Check Amount: ";
cin&gt;&gt;a;
}
while (! validFee(a));

cout&lt;&lt;"Check Amount:                          "&lt;&lt;a&lt;&lt;endl;



change(a, hunds, fifts, twents, tens, fives, ones);
change(a,  quar, dime, nick, penn);



}//endmain

double fee(double&amp; a)
{


if (a&gt;=0 &amp;&amp; a&lt;=100)
{
	a = a - 5;
	cout&lt;&lt;" Cashing Fee :              $5.00"&lt;&lt;endl;
	return a;
} // ends if
if (a&gt;100 &amp;&amp; a&lt;=500)

} // end change coins

Here is what I am trying to get it to do:

- Prompts to ask for Check amount

- You Input check amount, if it is more than 1000 it loops back and asks you again

- at this point it should take a fee out based on the amount, also it will tell you how much the fee was

- now it should take whats left after the fee and change that into bills and coins, but our instructor wanted us to use an overload function to separate the bills and coins but using the same name.

MegaloJntariac · Oct 20, 2009

OKay I figure out why it wouldnt take the fee, i forgot to call the package in the main.

now I need to figure out about the coins and bills issue

whitedragon551 · Oct 20, 2009

So you want to call coins and dollars with the same variable? Thats what I get from the last line of the OP. If so it wont work. The last value to be input for that specific variable is what will display there.

You can do function overloading from what I understand, our instructor told us to function overload it, as long as the argument is different it should work....maybe I overlooked something? Any suggestions?

whitedragon551 · Oct 20, 2009

Looks right to me. It could be something as simple as indenting that is throwing the code off. I know when I worked with Python an indent made a huge difference. Other than that I dont see where your using the same variable twice for the overload. Maybe make sure you have everything spelled right and are using the same variables for what you have to.

MegaloJntariac · Oct 20, 2009

change() is what I am overloading, I am using one for bills and one for coins.

I wonder if I give it a return and funnel that into a new function "display()" then maybe I can make it work.

I cant figure out how to declare that. my logic is off. and I dont know where

whitedragon551 · Oct 20, 2009

Its probably syntax.

ThatChevyGuy · Oct 20, 2009

wow c looks a lot simpler than java

lilmaniac2 · Oct 20, 2009

IO in c++ is alot simpler than java. Java you have to use the java VM.

OP I'll write the entire program for you for $50, pm me if you want. Its too hard to try and follow someone elses logic to debug

MegaloJntariac · Oct 20, 2009

Its too late, I got a 0, I even went in early to try to get help. He woulndt help me at all. This is bs.
