program

Dear sir,

(a) How to create the below program?

Write a program that produces a bill and coin breakdown for an amount of money. Initialize the amount in the float variable known as dollars and use the cents variable to keep track of the amount not yet converted to bills and coins. You will have to make use of integer arithmetic and the remainder in this program.

Variables:
dollars (float)
cents (int)

Output:
The coin breakdown for 7.73 dollars is:
Dollar bills: 7
Fifty cents: 1
Twenty cents: 1
Ten cents: 0
Five cents: 0
One cents: 3


(b) Refers to the below codes. Why the "5% Service Tax" amount can't be displayed?

#include <stdio.h>
#include <conio.h>

void main()
{
int qty_sundae;
int qty_meals;
int qty_meal;
float price_sundae = 1.05;
float price_meals = 4.50;
float price_meal = 6.10;
float amt_sundae;
float amt_meals;
float amt_meal;
float amount;
float tax;
float total;

clrscr();
printf("Enter no. of Sundae cones \t : ");
scanf("%i", &qty_sundae);
printf("Enter no. of Happy meals \t: ");
scanf("%i", &qty_meals);
printf("Enter no. of Extra value meal \t: ");
scanf("%i", &qty_meal);

printf("\nWelcome to MC Donald's\n");
printf("Your Bill,\n");

amt_sundae = qty_sundae * price_sundae;
printf("\t %i Sundae cones \t :RM %5.2f\n", qty_sundae, amt_sundae);

amt_meals = qty_meals * price_meals;
printf("\t %i Happy meals \t\t :RM %5.2f\n", qty_meals, amt_meals);

amt_meal = qty_meal * price_meal;
printf("\t %i Extra value meal \t :RM %5.2f\n\n", qty_meal, amt_meal);

amount = (amt_sundae + amt_meals + amt_meal);
tax = amount * 0.05;
printf("\t 5% Service Tax \t :RM %5.2f\n\n", tax);

total = amt_sundae + amt_meals + amt_meal + tax;
printf("Total Charges \t\t\t :RM %5.2f", total);
getch();
}


Thanks,

This looks like a school homework assignment. We will not do your homework for you.

Part a. you need to write the program yourself first and then if you have specific questions on programming and/or syntax then we can answer your questions.

Part b. you need to elaborate on your question more.

Please forgive Spookster for missing the fact that you did provide your code along with the assignment text, we get far too many who don't so it's almost a knee-jerk reflex to post that sort of a reply.

Look at your program again, where does the "amount" variable get it's value set?

I didn't miss any fact Roy. I believe they are asking for help on two different programs. No coding was provided for the first one Part (a). These are most likely school assignments though since it sounds like it was copied verbatim off an assignment sheet.

Spookster,

You're right, I quick scanned the message assumed the code matched the assignment. However, I still provided only a hint instead of an answer since I do think it's important for people to have to figure things out for themselves.
