MATLAB: How to save no variable

errorjsonno variablesave

This is my code.
 Lat = 30;
 Lon = 12;
 base_url =[ 'http://maps.googleapis.com/maps/api/geocode/json'];
 formatSpec = '%4.6f';
 LatLon = [num2str(Lat,formatSpec),',',num2str(Lon,formatSpec)];
 request_url = [base_url '?latlng=' LatLon '&sensor=true_or_false']
 docNode = urlread(request_url);
 data = json.load(docNode);
 n = size(data.results,2);
 i = 1;
 for i = 1:n
    a = data.results(1,i).types(1,1);
    b = data.results(1,i).formatted_address;
    if strcmp(a,'country') == 1
       sprintf(b)
    else if strcmp(a,'locality') == 1
            c = b;
       sprintf(c)      
        end
    end
end
 save('name.mat','b','c')
 name = load('name.mat','-mat');
 N = struct2cell(name);
When you run the above code , the following message will appear. Variable 'c' not found.
So, I want to save as " no data " when there is no value of c or b as the message. What should I do?

In your test assign something to your variable c
if strcmp(a,'country')
     sprintf(b)
     c='no data'
elseif strcmp(a,'locality')
     c = b;
     sprintf(c)      
end
