i've been working on this program that is suppose to use four parameters named quarters,dimes,nickels and pennies, which represent the number of quarters,dimes, pennies and nickels in a piggy bank.
i have to use a function called totamt(), to return dollar value of the number of quaters,dimes,nickels, and pennies passed to it. below is what i have, if anyone could give me a few pointers on what im doing wrong that would be great:

#include <iostream.h>
#include <stdlib.h>
#include <iomanip>

int main()
{ float t,v;
float totamt (float,float,float,float);
float total, value;
cout<<"enter a value";
cin>>value;
cout <<"the total value is"<<total<<endl;

system("PAUSE");
return 0;
}
float totamt(float q,float d,float n,float p,float t,float v)
{
if (v >= .25)
t =.25;
else if (v>=.10)
t =.10;
else if (v <=.01)
t =.01;
else if (v<=.05)
t =.05;
return totamt;

)

please read the "How to post" thread, and please use [code] tags. If you do this, you increase the responses, and their helpfullness.

i do not think it would be fair if i told you what you did wrong and explained it to you. But here is a version of what i thought you were trying to do. Im really not sure lol!

(Toggle Plain Text)

#include <iostream.h>
#include <stdlib.h>
#include <iomanip>

float totamt(float,float,float,float);

int main()
{ 
     float total,tq,td,tn,tp;
     
     cout << "how many quarters?";
     cin >> tq;
     cout << "how many dimes?";
     cin >> td;
     cout << "how many nickels?";
     cin >> tn;
     cout << "how many pennies?";
     cin >> tp;

     total=totamt(tq,td,tn,tp);

     cout << endl << "the total value is" << total << endl;

     system("pause");
     
     return 0;
}

float totamt(float q,float d,float n,float p)
{
     float tmpTotal;

     tmpTotal+=(q*.25);
     tmpTotal+=(d*.10);
     tmpTotal+=(n*.05);
     tmpTotal+=(p*.01);
    
     return tmpTotal;
}

EDIT: i personally did not run this code...

@Kilo: It's good you tried to help him, but you should use standard headers (iostream not iostream.h). Other than that, your code seems to work like intended.

@area: if you use kilo's code, make sure you change iostream.h to iostream, and then add the line using namespace std; after all of your includes.

Kilo · Nov 22nd, 2005, 5:54 PM

i just took his code and altered it... i changed nothing with his headers sorry

EDIT: and it depends on compiler also, i know MSVC++ 6.0 requires '.h'

No, it doesn't.

Kilo · Nov 22nd, 2005, 7:01 PM

yes it does.. i have used MSVC++ for 4 years you cannot include <iostream> must have '.h' there is no header directive

DaWei · Nov 22nd, 2005, 7:22 PM

Kilo, I have been using MSVC++ 6.0 for much longer than that. Would you like to see an example?

DaWei · Nov 22nd, 2005, 7:46 PM

Rather than compress this and possibly deter readability, the link is directly to my site: VC++ 6.0 Compilation. It's zoomable, if your resolution needs that.

Kilo · Nov 22nd, 2005, 7:47 PM

all i know is that on any computer with mscv++ i have ever used typing -> #include <iostream> creates and error... period nothing i can do to change that granddaddy bro? maybe you just so happen to have a header directive? if you feel it will work send me a cpp file with it doing so... i will run it and copy paste the error?
