Plot points with different symbols

I have a text file that contains x and y coordinates and one value that determine the "type" of the point.
File looks like this:
41 31 1
16 10 0
3 2 1
20 37 1
10 49 1
27 49 0
In each line (or row), the first value represents x coordinate, the second value represents y coordinate, and last value represents the "type" of the point.
I'd like to plot these points using '*' if it is a point of type 0, and 'O (blank circle)' if it is a point of type 1.
Could anyone help?

a=dlmread('file.txt')
x=a(:,1)
y=a(:,2);
ii=a(:,3);
idx=ii==1
scatter(x(idx),y(idx),'*')
hold on
scatter(x(~idx),y(~idx),'o')
