Question

Write the algorithm that determines the change to be dispensed from a vending machine. An item in the machine can cost between 5 cents and 1 dollar, in 5-cent increments (5,10,15,......90, 95, or 100), and the machine accepts only a single dollar bill to pay for the item. The user will provide the price and the program will output the price and calculate and output the total change and how many quarters, dimes and nickels need to be dispensed. DO NOT USE REPETITION OR SELECTION STATEMENTS TO SOLVE THIS--- You must use Div & Mod! (Division and Modulo)---- ( C++ )

Answer 1

Executable code:

import java.util.Scanner;
public class VendingMachine{
public static void main(String args[])
{
Scanner keyboard=new Scanner(System.in);
int n1,amount,n2,n3,n4,n5;
System.out.println("Enter price of item (from 20 cents to a dollar, in 5-cents):");
n1=keyboard.nextInt();
System.out.println("You bought an item for "+n1+" cents and gave me adollar");
System.out.println("So your change id");
amount=100-n1;
n2=amount/25;
amount=amount%25;
n3=amount/10;
amount=amount%10;
n4=amount/5;
amount=amount%5;
n5=amount;
System.out.println(n2+" quarters");
System.out.println(n3+" domes");
System.out.println(n4+" nickels");
System.out.println(n5+" pennies");
}
}

Output:
