Q1. What do the .data, .word, .text directives mean (i.e., what do you put in each section)? Q2. How do you set a breakpoint in MARS? Set breakpoint on line 15, give the command in your answer. Q3. After your program stops because of a breakpoint, how do you continue to execute your code? How do you step through your code? Q4. How can you find out the contents of a register? How do you modify the value of a register? Q5. At what address is n stored in memory? Calculate the 13th fib number by modifying this memory location. Q6. line 18 and 20 use syscal1 instruction.
