Due: midnight October 28, 2008

The objective of this assignment is to gain practice in writing functions using register conventions, and to utilize indexed addressing modes of the MIPS processor.

Write a function fib( int n, int &arr) to store the first n elements of the Fibonacci sequence into an array in memory. The value of n is passed in register $a0, and the address of the array is passed in register $a1.

Your main program will request values of n from the user in a loop until a value of zero is received. In each iteration of the loop, print the Fibonacci sequence calculated. Include appropriate prompts and error messages. For this assignment, the value of n must be a positive integer no greater than 25.
