  In this review, we discuss whether the present solar dynamo models can be
extrapolated to explain various aspects of stellar activity. We begin with a
summary of the following kinds of data for solar-like stars: (i) data
pertaining to stellar cycles from Ca H/K emission over many years; (ii) X-ray
data indicating hot coronal activity; (iii) starspot data (especially about
giant polar spots); and (iv) data pertaining to stellar superflares. Then we
describe the current status of solar dynamo modelling---giving an introduction
to the flux transport dynamo model, the currently favoured model for the solar
cycle. While an extrapolation of this model to solar-like stars can explain
some aspects of observational data, some other aspects of the data still remain
to be theoretically explained. It is not clear right now whether we need a
different kind of dynamo mechanism for stars having giant starspots or
producing very strong superflares.
