Question

Task 4: a) Write a function named change() that has an integer parameter and six integer reference parameters named hundreds, fifties, twenties, tens, fives, and ones. The function is to consider the passed integer value as a dollar amount and convert the value into the fewest number of equivalent bills. Using the reference parameters, the function should alter the arguments in the calling function. b) Include the function written in part a in a working program. Make sure your function is called from main() and returns a value to main() correctly. Have main() use a printf statement to display the returned value. Test the function by passing various data to it and verifying the returned value.

C/C+ program language

CODE:

#include <iostream>

using namespace std;
//method to return the change
void change(int amount,int *hundreds,int *fifties,int *twenties,int* tens,int *fives,int *ones){
//initializing the variables
*hundreds = 0; *fifties = 0; *twenties = 0; *tens = 0;*fives = 0;*ones = 0;
//if amount is greater than hundred then hundreds note can be used
if(amount >= 100){
*hundreds = amount/100;
//amount is revised
amount = amount%100;
}
if(amount >= 50){
//if the remaining amount is greater than 49 fifties can be used
*fifties = amount/50;
amount = amount%50;
}
if(amount >= 20){
//if the remaining amount is greater than 19 twenties can be used
*twenties = amount/20;
amount = amount%20;
}
if(amount >= 10){
//if the remaining amount is greater than 9 tens can be used
*tens = amount/10;
amount = amount%10;
}
if(amount >= 5){
//if the remaining amount is greater than 4 fives can be used
*fives = amount/5;
amount = amount%5;
}
if(amount >= 1){
//if the remaining amount is greater than 0 ones can be used
*ones = amount;
}
}

int main() {
//main method
int hundreds,fifties,twenties,tens,fives,ones;
int amount = 467;
//calling the function
change(amount,&hundreds,&fifties,&twenties,&tens,&fives,&ones);
cout<<"\nAmount: $"<<amount<<endl;
cout<<"Hundreds: "<<hundreds<<endl;
cout<<"Fifties: "<<fifties<<endl;
cout<<"Twenties: "<<twenties<<endl;
cout<<"Tens: "<<tens<<endl;
cout<<"Fives: "<<fives<<endl;
cout<<"Ones: "<<ones<<endl;

amount = 57;
//calling the function
change(amount,&hundreds,&fifties,&twenties,&tens,&fives,&ones);
cout<<"\nAmount: $"<<amount<<endl;
cout<<"Hundreds: "<<hundreds<<endl;
cout<<"Fifties: "<<fifties<<endl;
cout<<"Twenties: "<<twenties<<endl;
cout<<"Tens: "<<tens<<endl;
cout<<"Fives: "<<fives<<endl;
cout<<"Ones: "<<ones<<endl;

amount = 1037;
//calling the function
change(amount,&hundreds,&fifties,&twenties,&tens,&fives,&ones);
cout<<"\nAmount: $"<<amount<<endl;
cout<<"Hundreds: "<<hundreds<<endl;
cout<<"Fifties: "<<fifties<<endl;
cout<<"Twenties: "<<twenties<<endl;
cout<<"Tens: "<<tens<<endl;
cout<<"Fives: "<<fives<<endl;
cout<<"Ones: "<<ones<<endl;

return 0;
}
