well if you know that 
change in enthalpy dH = change in internal energy dU + dnRdT
now open all the terms 
ncpdt  = ncvdt  +nrdt
cancelling the underlined and bold letters
cv=cp-R

It arises from the first law of the thermodynamics 
  
  dq = dU + pdv …..........(1)
 for const pressure dq= n Cp dT
and dU= nCvdT  
always holds true .
PV=nRT------> Pdv= nRdT at const pressure 
Put all these in eqn. 1
       n Cp dT = nCvdT + n RdT
----------> C- Cv = R
