Mar 29, 2015 at 16:25 comment added m_goldberg You can also define a default value for c. For example, f[a_, b_, c_:3] := {a, b, c}. Then f[1, 2, 42] gives {1, 2, 42} and f[1, 2] gives {1, 2, 3}.
Mar 29, 2015 at 16:11 comment added Szabolcs See here and note that the lhs of := is really just a pattern and you can have "definitions" for as many patterns as you like. f[1]=2; f[a_,b_]=3; f[x_,y_,z_]:=x
