Answer:
Here is the JAVA program:
import java.util.Scanner; //to accept input from user
public class Main { //class name
public static void main(String[] args) { //start of main function
Scanner input =new Scanner(System.in); // creates Scanner class object
int amount, quarters, dimes, nickels, pennies,change; //declare variables
System.out.println("Enter the price of the(from 25 cents to a dollar, in 5-cent increments): "); //prompts user to enter the price
amount=input.nextInt(); //reads amount from user
change= 100-amount; //computes change
System.out.println("You bought an item for " + amount+" cents and gave me a dollar, so your change is :");
quarters=change/25; //computes quarters
change=change%25; //computes quarter remaining
if(quarters == 1) // if quarter is equal to 1
System.out.println(quarters+ " quarter"); //prints quarter value in singular
else if (quarters>1) // if value of quarters is greater than 1
System.out.println(quarters+" quarters"); //prints plural quarters value
dimes=change/10; //computes dimes
if(dimes == 1) // if value of dime is equal to 1
System.out.println(dimes+ " dime"); //prints single value of dimes
else if (dimes>1) //if value of dimes is greater than 1
System.out.println(dimes+" dimes"); //prints plural value of dimes
change=change%10; //computes dimes remaining
nickels=change/5; //computes nickels
if(nickels == 1) //if value of nickels is equal to 1
System.out.println(nickels+ " nickel"); //prints single value of nickels
else if (nickels>1) //if value of nickels is greater than 1
System.out.println(nickels+" nickels"); //prints plural value of nickels
change=change%5; //computes nickels remaining
pennies=change; //computes pennies
if(pennies == 1) //if value of pennies is equal to 1
System.out.println(pennies+ " penny"); //prints single value of pennies
else if (pennies>1) //if value of pennies is greater than 1
System.out.println(pennies+" pennies"); } } //prints plural value of pennies
Explanation:
I will explain the program with an example:
Suppose amount= 75
Then change = 100 - amount= 100 - 75 = 25
change = 25
quarters = change/25 = 25/25 = 1
quarters = 1
change = change % 25 = 25%25 = 0
dimes = 0/10 = 0
Now all other values are 0.
Now the following line is printed on screen:
You bought an item for 75 cents and gave me a dollar. Your change is:
Now program moves to if part
if quarters == 1
This is true because value of quarter is 1
sot "quarter" is displayed with the value of quarters
Now the following line is printed on screen:
1 quarter
So the complete output of the program is:
You bought an item for 75 cents and gave me a dollar. Your change is:
1 quarter
