Switch function to output number of days in a month

I am trying to use switch to output number of days for each month, however I am having issues with my input, Please advice.

here is my code:

n = input('Enter the month name: ');

switch n

case January

Days = '31';

otherwise

disp('Invalid month name');

return;

end

disp(['Days ', Days]);

Actually you need to use the optional 's' argument for input, otherwise your code will throw an error:

n = input('Enter the month name: ','s');
switch lower(n)
    ...
end
