C/C++ :: Create Billing System Without Using Pointers - Array Calculations

I am trying to create an billing system "without using pointers". This is my class assignment. In this,

1) User inputs the name
2) The system asks how many items he has purchased
3) Displays a bill number [just a random number]
4) System asks for the item names the user purchased and stores them in an array (of max 10 (ten) inputs (or items))
5) After each item the user inputs, the system asks for the price of the item (stored in an array of numbers)
6) The total bill is calculated, by adding the sum of all prices in the array

I am having terrible difficulties in coding #4 and #5. Somehow, they aren't going well together. Here's what I have:

#include<stdio.h>
#include <stdlib.h>
int main() {
char item[10][10], answer = 'y', name;
int price[10], total_item, total_price = 0, i, j, a, total_bill = 0, max_items = 10, max_char = 10;

[Code] ....

You might find a lot of unused variables
