I have started learning Octave today. 
In my attached photo, variale b is an 1x3 array and c is an 3x1 array.
Addition or subtraction of this to variable is not possible. Instead of
error message, i am getting answer which is a 3x3 matrix. what is the
problem?

There is no problem, this behaviour is called "broadcasting" :
