  For a continued progress in the pursuit of neutrino oscillation parameters,
we require to have a precise knowledge of the pion production processes which
act as a source of backgrounds and systematic uncertainties in neutrino
oscillation experiments because pions can mimic a final state electron
(positron). Therefore a pion production principal interaction may appear to be
quasi-elastic if the pion is absorbed in the final state interactions.
Charged-current single pion production processes induced by $\nu_{\mu}$ and
$\bar{\nu_{\mu}}$ interactions with hydrocarbon target $(CH_{2})$ has been
studied using NuWro event generator and the cross-sections so obtained have
been compared with the results of Miner$\nu$A experiment.
