im working on a basic till system

Code:

#include<stdio.h>

void asci(void);//function prototype

void till(void);//function prototype



int item;//declaring variables

int quantity;//declaring variables

int price;//declaring variables

int x;//inner loop counter

int y;//outer loop counter

int main(void){

asci();//function call

	int testnum = 0;

	do{

		printf("\nMenu Navigation\n0 = Exit\n1 = Item Input\nEnter a menu number = ");

		scanf_s("%d", &testnum);

		switch(testnum) {

		case 0 : continue;

	//now for the loop
	//yer baby the loop.........

		case 1 :till();//function call

			break;

		}

	

	} while(testnum !=0);

	printf("Loop complete\n");

		return 0;

	}

/**********************************************************************************/

	printf("\t%c",201);

		for(x=1;x<60;x++)

void till(void)//function definition - used for the till selection

	}
//end the wonderfull adding up code

how can i get it so that the user can keep entering an item and price and such untill 0 is pressed.
Also how can i output this information into a file or on screen?

What's scanf_s()?

Code:

puts("\nItems List\n");

First of all, this is C. It's the same as

Code:

cout << "\nItems List\n\n";

or

Code:

printf("\nItems List\n\n");

puts() adds a newline onto the end of the string.

how can i get it so that the user can keep entering an item and price and such untill 0 is pressed.

Use a while loop. Something like this:

Code:

int x;

while(scanf("%i", &x) && x) { // (or cin>>x)
    /* code */
}

Also how can i output this information into a file or on screen?

Onto the screen:

Code:

C:\directory>program

Into the file file:

Code:

C:\directory>program > file

Or you can program it yourself.

scanf_s is the new type of scan used in visual c++ 2005 express

**dwks** · 12-10-2005

Ugh! If you say so.

Isn't it C, though?

[edit]
Never mind, your whole program is C. Don't know what it's doing in here.

oh did i post it wrong?

**dwks** · 12-10-2005

Well, this is the C++ forum. You're supposed to put C programs in the C forum.

**neoapple** · 12-10-2005

ok sorry, anyway i have an issue i still cant figure put how to add the loop to my code.

**dwks** · 12-10-2005

You already have a loop.

[edit] Oh, you mean in till(). In that case, see main() for an example. [/edit]

**neoapple** · 12-10-2005

yes but i want it to continue adding items untill i press a button as right now i add one itema nd it goes back to main menu selection

**dwks** · 12-10-2005

As I said, see main().

Code:

void till(void)//function definition - used for the till selection

// here we add item name, quantity and price

{
	puts("\nItems List\n"); //main till functions, select items, select quantity, select price

		printf("Enter Item Name = "); //Item

		scanf_s("%d",&item);

		printf("Enter Quantity = "); //Quantity

		scanf_s("%d",&quantity);

		printf("Enter Price = "); //Price

		scanf_s("%d",&price);

	//this wonderfull code will add it all up for you

int multiply_stuff	= quantity * price; //this deals with the total item price of whats been ordered. 
										//quantity multiplyed by price = total
printf("Product Name: %d :: Item Quantity: %d :: Item Price: = %d :: Total For Item: = %d ",item,quantity, price, multiply_stuff);
	}

->

Code:

void till(void)//function definition - used for the till selection

// here we add item name, quantity and price

{
    while(1) {

	puts("\nItems List\n"); //main till functions, select items, select quantity, select price

		printf("Enter Item Name = "); //Item

		scanf_s("%d",&item);

    if(item == 0) break;

		printf("Enter Quantity = "); //Quantity

		scanf_s("%d",&quantity);

		printf("Enter Price = "); //Price

		scanf_s("%d",&price);

	//this wonderfull code will add it all up for you

int multiply_stuff	= quantity * price; //this deals with the total item price of whats been ordered. 
										//quantity multiplyed by price = total
printf("Product Name: %d :: Item Quantity: %d :: Item Price: = %d :: Total For Item: = %d ",item,quantity, price, multiply_stuff);
}
	}
