### A good answer might be:

Yes. However, the stack may grow as the subroutine executes. But the frame pointer for the subroutine does not change. The stack pointer (`$sp`) is always equal to the top of stack.

# Sample Code

Imagine that the following statement is part of the subroutine whose stack frame is at right:

    a = b + i + j;

This is how a compiler might implement that statement:

    lw    $t0,8($fp)     # get b
    lw    $t1,4($fp)     # get i
    lw    $t2,0($fp)     # get j
    addu  $t3,$t0,$t1    # b + i
    addu  $t3,$t3,$t2    # b + i + j
    sw    $t3,12($fp)    # a =

### QUESTION 5:

Play compiler: translate the following statement into assembly language:

    a = a + 1;
