% Use DIS's READINT function (see lectures):
size = readInt(1,10,'Enter a size [1,10]: ');

% Special case:
% Print first row
% Could have folded this into main algorithm
for col=1:size-1
    fprintf(' ');
end
fprintf('*\n');

% Print subsequent rows of stars by
% printing blanks, then a star, then blanks
% then a final star:
for row=2:size
    for col=1:size-row
        fprintf(' ');
    end
    fprintf('*');
    for col=size-row+2:size-1
        if row < size
            fprintf(' ');
        else
            fprintf('*'); % for last row
        end
    end
    fprintf('*\n');
end
