How to read user input of multiple string separately in inputdlg

I want to enter user input using inputdlg,

if true
  % prompt = {'Input the number of Criteria','Input short name of criteria'};
      dlg_title = 'Alternative Evauation';
      num_lines = 1;
      defaultans = {'3','{Criteria1,Criteria2,Criteria3}'};
      answer = inputdlg(prompt,dlg_title,num_lines,defaultans);
end       
although I am able to read 'number of Criteria' as 
n=str2num(answer{1})
but when I try to read the read the short name of criteria
as
str=answer{2}
then instead of reading str as 'Criteria1', 'Criteria2', 'Criteria3'separately, it reads as Criteria1Criteria2Criteria3,

Please tell me how can I handle the multiple string input separately.

Thanks

Here's a snippet I post regularly:

% 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 usersValue1 for validity.
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.\nTry replacing the user.\nI will use %.2f and continue.', usersValue1);
    uiwait(warndlg(message));
end
% Do the same for usersValue2
% Check usersValue2 for validity.
if isnan(usersValue2)
    % 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 usersValue2.
    usersValue2 = str2double(defaultValue{2});
    message = sprintf('I said it had to be a number.\nTry replacing the user.\nI will use %.2f and continue.', usersValue2);
    uiwait(warndlg(message));
end

Try this instead:

prompt = {'Input the number of Criteria','Input short name of Criterion 1','Input short name of Criterion 2','Input short name of Criterion 3'};
      dlg_title = 'Alternative Evauation';
      num_lines = [1 20];
      defaultans = {'3','Criterion 1','Criterion 2','Criterion 3'};
      answer = inputdlg(prompt,dlg_title,num_lines,defaultans);

@Star Strider Thank you very much for your response, but there is no limit on inputting the number of criterion, it may be 5 or 7, depending upon the User, so accordingly name of criterion will increase, how to tackle that. Later on I want to concatenate all the input names of criterion into single variable.

My pleasure.

You will have to experiment on your own to get the inputdlg function to do what you want, if you want it to be adaptable. One way would be to set up the maximum number of criteria you believe would ever be needed, and test for the response being different from the default. Or ask first in another inputdlg for the number the user will provide, then dynamically design the second inputdlg to accommodate that number.
