This paper presents a systematic study of charged pion and proton production in inelastic p&sup(12)C and d&sup(12)C collisions at a beam momentum of 4.2~GeV/c per nucleon as a function of collision centrality, which is characterized by the net charge Q of secondary particles serving as an experimental estimator of the number of participating nucleons. We analyze the average multiplicities and kinematic characteristics of *p&sup(+) , *p&sup(-) , and protons, including the mean momentum (p) , transverse momentum (p&sub(T)) , emission angle <*y> , and rapidity (y) . The experimental results are compared in detail with predictions of the FRITIOF model, which provides a satisfactory overall description of the particle multiplicities. A clear centrality dependence is observed: with increasing Q , the average momentum of pions decreases while their mean emission angle increases, indicating an enhanced role of secondary intranuclear interactions. These effects are more pronounced in pC than in dC collisions. The data presented in this work provide a quantitative benchmark for hadronic transport models in the few-GeV energy range.
