Problem $3.(4$ points$)$:

This problem concerns the indexing of $C$ arrays.

Consider the $C$ code below, where $N$ is a constant declared with #define.

int foo $($int $A[16][N],$ int $i,$ int $j)$

$\{$

return $A[i][j]$;

$\}$

Suppose the above $C$ code generates the following assembly code:

foo:

push$1\%$ebp

movl $\%$esp,$\%$ebp

movl $8(\%$ebp$),\%$ecx

movl $16(\%$ebp$),\%$edx

movl $12(\%$ebp$),\%$eax

sal$1$ $$2,\%$edx

sal$1$ $$3,\%$eax

subl $12(\%$ebp$),\%$eax

leal $(\%$edx,$\%$eax, $4),\%$eax

movl $\%$ebp,$\%$esp

popl $\%$ ebp

movl $(\%$ecx,$\%$eax$),\%$eax

ret

What is the value of $N?$

$N=$
