save data to cell array

I need to save all this data into a cell array in order for my function to work. Can someone please assist me??

while 1
 
shapeList = {'Circle','Square','Ellipse','Triangle','Rectangle'};
[selection,ok] = listdlg('PromptString','Select the next shape:',...
                         'SelectionMode','single',...
                         'OKString','Enter',...
                         'CancelString','No more',...
                         'ListString',shapeList);
 if ~ok 
    break; 
end
                
switch selection
    case 1
        shape='Circle';
    case 2
        shape='Square';
    case 3
        shape='Ellipse';
    case 4
        shape='Triangle';
    case 5
        shape='Rectangle';
end
                  
shapecounter=shapecounter+1;
 
 
switch selection
    case 1
        prompt={'Enter diameter'};
    case 2
        prompt={'Enter side length dimension'};
    case 3
        prompt={'Enter major diameter','Enter minor diameter'};
    case 4
        prompt={'Enter base dimension', 'Enter height dimension'};
    case 5
        prompt={'Enter height', 'Enter width'};
        
end
 
firstdim=str2num(inputvalues{1});
 
if length(inputvalues)> 1
    seconddim=str2num(inputvalues{2});
end
 

if isempty(ok)
    colour='No_Colour';
else
    
switch selectionC
    case 1
        colour='Red';
    case 2
        colour='Yellow';
    case 3
        colour='Blue';
    case 4
        colour='Green';
    case 5
        colour='Orange';
    case 6
        colour='Violet';
    otherwise 
        colour='No_Colour';
end
end
 
 
switch selection
    case 1
        area=pi*(firstdim/2)^2;
    case 2
        area=firstdim^2;
    case 3
        area=pi*(firstdim/2)*(seconddim/2);
    case 4
        area=0.5*firstdim*seconddim;
    case 5
        area=firstdim*seconddim;
end
 
end
 
 
Print_Me(shape);

you either use the {} to store things in cell array

e.g.

a = {shape colour area};

or you can create a cell array and use index to store

a = cell(1,3);
a{1} = shape;
a{2} = colour;
a{3} = area;

Okay thank you!! but now it is saving only the last shape, area, and colour that I put in, it is not saving the ones before that. How do I fix this problem and get it to continually save each shape, area, and colour?

As suggested by Mohammad Sami, you can use the cell array as described by him. Apart from that, you can significantly simplify your code by removing unnecessary the switch-case blocks. For example, try

counter = 1;
while 1
    
    shapeList = {'Circle','Square','Ellipse','Triangle','Rectangle'};
    [selection,ok] = listdlg('PromptString','Select the next shape:',...
        'SelectionMode','single',...
        'OKString','Enter',...
        'CancelString','No more',...
        'ListString',shapeList);
    if ~ok
        break;
    end
    
    shape{counter} = shapeList{selection};
    
    prompt_list = {'Enter diameter', 'Enter side length dimension', ...
        {'Enter major diameter','Enter minor diameter'}, ...
        {'Enter base dimension', 'Enter height dimension'}, ...
        {'Enter height', 'Enter width'}};
    prompt = prompt_list{selection};
    
    %
    % ask for inputvalues
    %
    inputvalues = {'1'}; % for example
    firstdim=str2num(inputvalues{1});
    if length(inputvalues{1})> 1
        seconddim=str2num(inputvalues{2});
    end
    
    
    if isempty(ok)
        colour{counter}='No_Colour';
    else
        colour_list = {'Red', 'Yellow', 'Blue', 'Green', 'Violet', 'No_Colour'};
        colour{counter} = colour_list{selection};
    end
    
    switch selection
        case 1
            area{counter}=pi*(firstdim/2)^2;
        case 2
            area{counter}=firstdim^2;
        case 3
            area{counter}=pi*(firstdim/2)*(seconddim/2);
        case 4
            area{counter}=0.5*firstdim*seconddim;
        case 5
            area{counter}=firstdim*seconddim;
    end
    counter = counter + 1;
end

Check the values of shape, colour and area variables.
