How carry and zero flag bits are modified after CMP instruction is executed?
The instruction format is CMP R1, R2. How will the carry and zero flags we be modified after above instruction is executed? Case 1: R1< R2 Carry Flag = 1 Zero Flag = 0 R1= R2 Carry Flag = 0 Zero Flag = 1 R1> R2 ... 0 Zero Flag = 1 R1> R2 Carry Flag = 1 Zero Flag = 0 Which one of the above two cases is correct?

Preparation advice
hey guys! I am a final year student and preparing for gate 19. Preparation is going well but the problem I am facing is with time left. Since 2 months are left for the exams and semester exams are also round the corner, so I am thinking of skipping over ... and previous years questions. Though I will be taking full Mock tests for sure. Is it a wise choice. Need some advice. :)
