All of the employees at the AcmeSoft company are either programmers or salespeople. The programmers always tell the truth, the salespeople always lie.

Three AcmeSoft employees - A, B, and C - were standing together in the hallway. A visitor passed by and asked A, "Are you a programmer or a salesperson?" A mumbled an answer that the visitor could not hear clearly. The visitor then asked B, "What did A say?" B replied, "A said that he is a salesperson." At this point, the third employee, C, said, "Don't believe B; he is lying!"

What are B and C?
