Need help using fprintf for cell array

I have a structure named 'shape' that contains three sub-structures ('circle', 'triangle', 'square') and need to print them out in a list. Here is my code:

%Create shape super-structure.

shape = struct('circle', [], 'triangle', [], 'square', []);

%Print names of created shapes.

fields = fieldnames(shape);

fprintf('You created these shapes:\n%s\n', fields{:});

I need the command window to show this... You created these shapes:

circle

triangle

square

...but instead, it prints "You created these shapes:" before every single shape. How should I go about fixing this?

Also, please use the code formattting.

Give this a go:

shape = struct('circle', [], 'triangle', [], 'square', []);
 
%Print names of created shapes.
fields = fieldnames(shape);
% fprintf('You created these shapes:\n%s\n', fields{:});
fprintf('You created these shapes:\n');
fprintf('%s\n',fields{:})

You need to seperate the first line from the rest if you don't want repeats.
