Q$7.$

$//6$ marks $(3+3)$

a$.$ If a C$/$C$++$ compiler is compiling a C$/$C$++$ code with an int$8\_$t $(8$ bits signed $2\text{'}$s complement$)a=043,$ and must multiply it by int $8_{t}b=2.$ The result must be saved as a $\frac{C}{?}$ C$++$ int$8\_$t$.$ What is the most efficient way to achieve it in Assembly. You need to only specify the operation, not necessarily an instruction from any particular ISA.

b$.$ Is the result of the operation in part a$,$ the correct result of multiplying the original signed number by $2.$
