The production of heavy flavour quarks in association with a vector boson represents an important process to study QCD. High precision is achieved in measurements of differential cross sections and comparisons are made to state-of-the-art NLO QCD calculations and different parton distribution function parameterizations. Measurement of the production of a W boson in association with a charm quark using 4.6 fb-1 of pp collisions at sqrt(s) = 7 TeV with the ATLAS detector is reported. The measurement is performed using W boson plus tagged c-jet and W boson plus D/D* meson. Cross sections integrated over a fiducial kinematic range and differential as a function of the pseudorapidity of the lepton from the W-boson decay are reported.
