Required I$/$O:

F$.$ Last is your first initial and last name.

Hints:

The format argument will be passed to printf in $$a0,$ preserve $$a0?$

The variable arguments will be passed to printf in the reverse order. For example:

$$format cstring", p$1,$ p$2,$ p$3$

$a$0->$ "format cstring"

stack:

high $[$ p$3]8$

$[$ p$2]4$

low $[p1]0$

Set pointer to the first parameter:

Retrieve first parameter: $($$t$9)$

Get ready for the next parameter: $t9=t9+4$

Retrieve second parameter: $($$$t9)$

Get ready for the next parameter: $t9=t9+4$

$...$

The caller is responsible for creating and removing the variable arguments on the stack.

MUST BE IN MIPS ASSEMBLY LANGUAGE :

$1.$ Implement the procedure printf:

void printf$($cstring format, parameters...$)$

format:

$\%\%-$ output $\%$

$\%$d $$ output the next parameter as an integer $($syscall $1)$

$\%$s $$ output the next parameter as a cstring $($syscall $4)$

This procedure is similar to Java System.out.printf or C$/$C$++$ printf. For unknown $\%$code, printf will

output $?$code and terminate. For example: "hello $\%$z there" will output:

hello $?$z

$2.$ Provide a test main that will call printf with different parameters.
