  Type Ib/c supernovae (SNe Ib/c) mark the deaths of hydrogen-deficient massive
stars. The evolutionary scenarios for SNe Ib/c progenitors involve many
important physical processes including mass loss by winds and its metallicity
dependence, stellar rotation, and binary interactions. This makes SNe Ib/c an
excellent test bed for stellar evolution theory. We review the main results of
evolutionary models for SN Ib/c progenitors available in the literature and
their confrontation with recent observations. We argue that the nature of SN
Ib/c progenitors can be significantly different for single and binary systems,
and that binary evolution models can explain the ejecta masses derived from SN
Ib/c light curves, the distribution of SN Ib/c sites in their host galaxies,
and the optical magnitudes of the tentative progenitor candidate of iPTF13bvn.
We emphasize the importance of early-time observations of light curves and
spectra, accurate measurements of helium mass in SN Ib/c ejecta, and systematic
studies about the metallicity dependence of SN Ib/c properties, to better
constrain theories.
