USE MIPS $-$A real$-$estate database is constructed in C using an array of structs that holds data on houses. A program automatically raises the taxes on each house by $$500$ each year.

struct house

$1$

int sqft;

int taxes;

char address $[100]$;

$\}$ ;

int main$()$

$1$

struct house homedbase $[1000]$;

int $i=0$;

while $)(1000\{$

homedbase $[$i$].$taxes $+=500$;

$i=i+1$

$\}$

$\}$

a$.$ Show how to allocate space for the empty database using assembler directives. Assume that ints are $4$ bytes and chars are $1$ byte. Use the $.$space directive with a label "homedbase:".

b$.$ On the back of this page, convert the while loop to assembly language. Use $ to for variable i$,$ and $$t1$ $$t9$ for other temporaries as needed.

Tips:

Write the basic while loop first and then put the memory accesses inside of it$.$

Since $BE\frac{Q}{B}$NEs require registers, you'll need to put $1000$ in a temporary.

You'll need to keep track of the offset from the base of the array to the current house's record

Use an additional counter register inside the loop that starts at the beginning of the homedbase and counts up by the size of the individual structs.
