Program counter holds the address of either the first byte of the next instruction to be fetched for exectuion or the address of the next byte of a multi byte instruction, which has not beeb completely fetched. in both the cases it gets increnented automatically one by one as the instruction bytes get fetched.

In binary representation there are some states that believed to be never occurred due to some particular functionality of a given circuit. If zero output is assigned to such states then it is called minimal risk solution as  we are resetting the formidable states which could be occurred accidentally. Another approach is to assigned a don't care to them so it results in lesser logic and hence is called minimal cost solution.
