I am having trouble with a loop. i can get the program to ask for the quantity and compute the same price for a certain amount of items, but i need it to loop and ask for the price of number(n) of items input by the user. it needs to be set up where they enter a number of items (n)and the program lets them enter the prices on that certain amount of items (n). can someone pease give me a little help with the loop. i used notes and slides i was given in class to do what i have so far but he hasnt really gone over loops that much and im new to programming.
Code:
/* Cash register simulator with change machine */
#include <stdio.h>
#include <stdlib.h>
int main( void )
{
int items; /* item qty purchased */
double price; /* item price */
double itemTotal; /* item total price */
double total = 0; /* customer total bill */
double amtPaid; /* amount paid by customer */
double change; /* change due customer */
int centsLeft; /* cents left to pay in change */
printf(" checkout line\n\n"
"Enter 0 for items to see total bill.\n\n");
printf("enter number of items: "); /* input */
scanf("%d", &items);
while( items != 0 )
{
printf("Price: ");
scanf("%lf", &price);
itemTotal = items * price;
printf("Item total: %.2f", itemTotal); /* display totals */
total += itemTotal; /* add to total bill */
printf("\n\nenter number of items: "); /* working input */
scanf("%d", &items);
}
printf("\n--------------------------\n"); /* totals */
printf("Customer total: %8.2f\n", total);
printf("Total due: %8.2f\n\n", total );
printf("\n\n");
system("PAUSE");
return 0;
}
