Need function and code in C/C++ for MATLAB
Promotion 1: If they buy six items or more they get 20% off on their most expensive item. Promotion 2: If their bill total (before tax) is greater than $100 they will get 10% off their entire bill. Customers can combine this deal with promotion 1 if their total bill is still over $100 after the 20% reduction on their most expensive item.
Write a function named cashRegister to implement this promotion. Your function should accept two inputs in the following order:
1. A single 1x2 cell array. The first cell contains a single column cell array of character vectors describing the items to be purchased. The second cell contains a column vector that represents the corresponding prices of those items.
2. A scalar variable with the sales tax rate in decimal form (e.g. 8.8% sales tax would be an input of 0.088).
The function should calculate the final bill by implementing the promotion described above and applying the input sales tax rate of 8.8% to the pre-tax subtotal. The function should generate the following three outputs:
1. A scalar variable representing the total savings from promotion 1 (promotion1). Assign this variable the value 0 if the purchase did not qualify for this promotion.
2. A scalar variable representing the total savings from promotion 2 (promotion2). Assign this variable the value 0 if the purchase did not qualify for this promotion.
3. A scalar variable representing the total bill (totalBill).
Function:
function [promotion1, promotion2, totalBill] = cashRegister(itemList, taxRate)
Code to call your function:
%example purchase that satisfies criteria for both promotions
itemDescriptions = {'Dice Set'; 'Model Car'; 'Jump Rope'; 'Science Kit'; 'Puzzle'; 'Board Game'; 'Stuffed Animal'};
itemCosts = [7.98; 14.99; 8.99; 34.95; 21.99; 19.99; 11.95];
itemList = {itemDescriptions, itemCosts};
taxRate = 0.088;
[promotion1, promotion2, totalBill] = cashRegister(itemList, taxRate)

Are the first two outputs correct for a purchase that only qualifies for promotion 1?
Is the total bill (third output) correct for a purchase that only qualifies for promotion 1?
Are the first two outputs correct for a different purchase that only satisfies promotion 2?
Are all three outputs correct for a purchase that satisfies both promotions?
Are all three outputs correct for a purchase that does not qualify for any promotions?
Are all three outputs correct for a purchase that does not qualify for any promotions?
