What happens in the following code? (you can start by running it and looking at the memory; note that you will need the –no_end flag)

func main():
    [fp + 1] = 2; ap++
    [fp] = 5201798304953761792; ap++
    jmp rel -1
end

Edit the loop my_loop in the exercise below so that it starts by writing 10 to [ap], continues by writing the decreasing sequence  and then returns. Don’t forget the ret instruction. Verify that your code works as expected by looking at the memory.

func main():
    [ap] = 2; ap++

    my_loop:
    [ap] = [ap - 1] * [ap - 1]; ap++
    [ap] = [ap - 1] + 1; ap++
    jmp my_loop
end

What does the following code do? (run with –no_end –step=16 to avoid the End of program was not reached error)

func main():
    [ap] = 2; ap++

    my_loop:
    [ap] = [ap - 1] * [ap - 1]; ap++
    [ap] = [ap - 1] + 1; ap++
    jmp my_loop
end
