  A realization of various algebraic structures in terms of the
$C_{\lambda}$-extended oscillator algebras is introduced. In particular, the
$C_{\lambda}$-extended oscillator algebras realization of
Fairlie-Fletcher-Zachos (FFZ)algebra is given. This latter lead easily to the
realization of the quantum $U_t(sl(2))$ algebra. The new deformed Virasoro
algebra is also presented.
