How can I do this program ?

Hashem - what have you tried so far? Please show your work and explain any difficulties you are experiencing with your code.

I did this so far, however I did not know how to do the switch statement and a while loop to keep asking the customer if they are done with the order.

Here's a snippet that may help. It lets you ask the user for numbers:

% Ask user for two floating point numbers.
defaultValue = {'45.67', '78.91'};
titleBar = 'Enter a value';
userPrompt = {'Enter floating point number 1 : ', 'Enter floating point number 2: '};
caUserInput = inputdlg(userPrompt, titleBar, 1, defaultValue);
if isempty(caUserInput),return,end; % Bail out if they clicked Cancel.
% Convert to floating point from string.
usersValue1 = str2double(caUserInput{1})
usersValue2 = str2double(caUserInput{2})
% Check for a valid number.
if isnan(usersValue1)
    % They didn't enter a number.  
    % They clicked Cancel, or entered a character, symbols, or something else not allowed.
  % Convert the default from a string and stick that into usersValue1.
    usersValue1 = str2double(defaultValue{1});
    message = sprintf('I said it had to be a number.\nI will use %.2f and continue.', usersValue1);
    uiwait(warndlg(message));
end

Also check out the fprintf() function so that you can print up the list for the user.

I want it with switch statement and a while loop

OK. So do that. The help has examples for those. Did you try to try them or adapt them??? How else is your homework going to get done? We can't just do the whole thing for you.
