Question
hey vijay thank u for answering the previous quesktion?

i have got one more quesktion?
i trying to create the system like the piggy bank.
but it is showing me wrong calcualtion.
if it is possible to change long in double and do the calcualtion
i tryden with double it wasnt working

#include <iostream>

using namespace std;

void main()
{
// Programmer: Mike Gozdiskowski
// Date: 9/13/2002
// Discussion: An interactive program to calculate the change
// from a vending machine

// Input: Cost of item purchased (an integer between 0 and 100 inclusive)
// Output: Change is Twohundert, Hundert, fifty, and cents

// Declaration and description of variables
// Declaration and description of variables
long cost;   // Cost of item purchased in cents
long change;   // Amount of change in cents
long Twohundert;   // Number of Twohundert in change
long Hundert;  //Number of Hundert in change
long fifty;  //Number of fifty in change
long twenty;  //Number of twenty in change
long thk;
long tempchange;
long ten;
long five;
long two;
long one;

// Welcome user and get amount of purchase
cout<<"Welcome to the cash register!"<<endl;
cout<<"Please enter the amount of your purchase: ";
cin>>cost;
cout<<"Please enter the amount of change: ";
cin>>thk;
// Calculate the total change due
change=(thk-cost);

Twohundert=change/200;
Hundert=(change%200)/100;
fifty=(change%100)/50;
twenty=(change%50)/20;
ten=(change%20)/10;
five=(change%10)/5;
two=(change%5)/2;
one=(change%2)/1;

/

cout<<"\t\t"<<"Total change due: "<<change<<" cents"<<endl;
cout<<"\t\t"<<Twohundert<<"\t"<<(char)156<<"2 Coin's"<<endl;
cout<<"\t\t"<<Hundert<<"\t"<<(char)156<<"1 Coin's"<<endl;
cout<<"\t\t"<<fifty<< "\t50p"<<endl;
cout<<"\t\t"<<twenty<< "\t20p"<<endl;
cout<<"\t\t"<<ten<< "\t10p"<<endl;
cout<<"\t\t"<<five<< "\t5p"<<endl;
cout<<"\t\t"<<two<< "\t2p"<<endl;
cout<<"\t\t"<<one<< "\t1p"<<endl;

tempchange = change;
while (tempchange > 0)
{
if (tempchange > 200)
{tempchange = tempchange-200;
Twohundert=Twohundert+1;}

else if (tempchange > 100)
{tempchange = tempchange-100;
Hundert=Hundert+1;}

else if (tempchange > 50)
{tempchange = tempchange-50;
fifty=fifty+1;}

else if (tempchange > 20)
{tempchange = tempchange-20;
twenty=twenty+1;}

else if (tempchange > 10)
{tempchange = tempchange-10;
ten=ten+1;}

else if (tempchange > 5)
{tempchange = tempchange-5;
five=five+1;}

else if (tempchange > 2)
{tempchange = tempchange-2;
two=two+1;}

else if (tempchange > 1)
{tempchange = tempchange-1;
one=one+1;}
}

}

Suppose the change in cents is 534.

534 / 200 == 2 is the number of 200 cent coins

534 % 200 == 134 is the remainder

134 / 100 == 1 is the number of 100 cent coins

134 % 100 == 34 is the remainder

34 / 20 == 1 is the number of 20 cent coins

34 % 20 == 14 is the remainder

and so on

int change_in_cents ;

// ...

// compute change_in_cents

int _200 = change_in_cents / 200 ;
change_in_cents %= 200 ;

int _100 = change_in_cents / 100 ;
change_in_cents %= 100 ;

int _50 = change_in_cents / 50 ;
change_in_cents %= 50 ;

// and so on

C++
