MATLAB CODE

clc;clear all;
Price = [2.98 4.5 9.8 4.5 3.85];
fprintf('MENU ');
fprintf(' _______________________________________________ ');
fprintf('| Deseart Number | Unit Price($) | ');
fprintf(' _______________________________________________ ');
for i =1:length(Price);
    fprintf('| %d | %2.2f | ',i,Price(i));
    fprintf(' _______________________________________________ ');
end
ext = 1;
fprintf('Please enter your order. Press 0 to stop ordering! Thank you :) ');
while ext
    Number(ext) = input('Dessert Number:');
    if(Number(ext) ==0)
        ext =0;
    else
        Quantity(ext) = input('Quantity sold:');
        ext = ext+1;
    end
end

SubTotal =0;
fprintf('Bill ');
fprintf(' ________________________________________________________ ');
fprintf('| Deseart Number | Unit Price($) | Quantity sold | Total | ');
fprintf(' ________________________________________________________ ');
for i =1:length(Quantity);
    switch(Number(i))
        case 1
            p = Price(1);
            total = p*Quantity(i);
        case 2
            p = Price(2);
            total = p*Quantity(i);
        case 3
            p = Price(3);
            total = p*Quantity(i);
        case 4
            p = Price(4);
            total = p*Quantity(i);
        case 5
            p = Price(5);
            total = p*Quantity(i);
    end
    SubTotal = SubTotal+total;
    fprintf('| %d | %2.2f | %d | %3.2f | ',Number(i),p,Quantity(i),total);
   fprintf(' ________________________________________________________ ');
end
fprintf('| Sub Total: %5.2f | ',SubTotal);
fprintf(' ________________________________________________________ ');
