I need Help !

**caulson** · 02-21-2011

Write a C program to help a HiFi’s Restaurant automate its breakfast billing system. Your assignment should implement the following items:

a.Show the customer the different breakfast items offered by the HiFi’s Restaurant.
b. Allow the customer to select more than one item from the menu.
c. Calculate and print the bill to the customer.
d. Produce a report to present your complete program and show more sample output.

Assume that the HiFi’s Restaurant offers the following breakfast menu:

Plain Egg $2.50
Bacon and Egg $3.45
Muffin $2.20
French Toast $2.95
Fruit Basket $3.45
Cereal $0.70
Coffee $1.50
Tea $1.80

Your program must do the following task below:

a. Define the data structs, menu item types with two components: menu item of type string and menu price of type double. Use an array to declare the data structs.
b. Function get data to loads the data into the array menu list.
c. Function show menu to show the different breakfast items offered by the restaurant and tell the user how to select the items.
d. Function print receipt to calculates and prints the customer receipt. The billing amount should include a 5% tax.
e. Format your output with two decimal places. The name of each item in the output must be left-justify. You may assume that the user selects only one item of a particular type.

This is my assignment, anyone can me some ideas ?
thank you.

Welcome to the forum Caulson!

Now get started on your program, ASAP. Because we HELP you in C, but you have to have some C for us to help you with.

Post up your program when you get stumped, and tell us what's the problem. The more specific you are describing the problem(s), the more detailed your help can be.

This is NOT a "we do your homework for you", forum. You have to take the lead, and get some skin into the coding.

This shows the basic logic you need for your menu display:
using for loop and functions to create a basic menu

We're not here to do your homework for you. Put some effort into it, and if something goes wrong, read man pages, and Google around for help. Use the forums as a last resort.

Hi, Here is my code. Anyone can give me some idea how to do a calculation part

thank you.

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

main()
{

char selection;
printf("\n Menu");
printf("\n 1 - plain egg");
printf("\n 2 - bacon and egg");
printf("\n 3 - Muffin");
printf("\n 4 - French Toast");
printf("\n 5 - Fruit basket");
printf("\n 6 - Cereal");
printf("\n 7 - coffee");
printf("\n 8 - Tea");
printf("\n Enter selection: ");
scanf("%c", &selection);

switch (selection)
{
case '1': printf("\plain egg\n");
break;
case '2': printf("\n bacon and egg\n");
break;
case '3': printf("\n Muffin\n");
break;
case '4': printf("\n French Toast\n");
break;
case '5': printf("\n Fruit Basket\n");
break;
case '6': printf("\n Cereal\n");
break;
case '7': printf("\n Coffee\n");
break;
case '8': printf("\n Tea\n");
break;
default : printf("\n Invalid selection\n");
}
getch();
return 0;

}

Two things you need right away:

1) Put your code between code tags. That keeps your code, looking like code, and easy to study.

Click on the # icon in the editor, to get a pair of code tags. You can insert code tags manually by typing
[code ] <<== I added an extra space so you could see the tag raw. Use no space in yours

Code:

 before the actual code starts

and [/code ] after it ends. <<== same as above. No spaces in your real code tags, of course.

2) You didn't put in the do while loop, like my link to you showed. You will HAVE to have the menu show itself multiple times, so people can order multiple things from it.

Check out that code I linked to, and add a do while loop. You can edit your post with the code, to include proper code tags.

Do you know how to use structs yet?

Add a getchar() after the scanf() for selection, to remove the newline left behind.

Are you in the same class as the guy who posted this thread ??

**livid** · 02-23-2011

Read the question carefully.The main function has to call showmenu() and take input as to what the user wants to eat and then pass this input to getdata().getdata() has to return the prices of the food items and those prices should be passed to printreceipt() where you print the bill.Try out accordingly.
Hope this helps

Hi, thank you for the reply. i dont know how to use struct program..anyone get the example ?

**anduril462** · 02-23-2011

There's a slew of tutorials here, including one on structs: Cprogramming.com - Programming Tutorials: C++ Made Easy and C Made Easy.

Add an double variable to keep track of the total. When a user selects a menu item, add the correct amount to their total. Add a "proceed to checkout" menu item, and if the user selects that, show them their total and exit.

Make sure you assign this variable to 0 before the program starts.

To make floating-point numbers stop printing after a specific decimal place, call printf like this.

Code:

printf("%0.2f hello world %0.3f hello world\n", float1, float2);

This will print float1 to the second decimal place, and float2 to the third decimal place. If you don't do this, your program will print five extra zeroes after the float.

Hi, this is the calculation part i done...anyone can tell me how to make a linking with two file ?
thank you

#include<stdio.h>
#include <conio.h>
#define s 10
struct menu
{
char item[8];
double price;
}menu[s];

int main()
{
int i, q;
printf("Enter quantity?<===%d",s);
scanf("%d", &q);
fflush(stdin);
for(i=0; i < q; i++)
{
printf("Enter name item- %d\n", i+1);
gets(menu[i].item);
fflush(stdin);
printf("Price");
scanf("%1.2f", &menu[i].price);
fflush(stdin);
}
for (i=0; i < q; i++) {
printf("rekod item: %s", menu[i].item);
printf("Price: %1.2f\n", menu[i].price);
getch();

}
}

I don't see code tags being used. If you don't read what we write, why should we read what you write? Right?

Code:
