Question $1$: $(1$point$)$

Assume the following rules of associativity and precedence for expressions: Precedence HighestShow the order of evaluation of the following expressions by parenthesizing all subexpressions and placing a superscript on the right parenthesis to indicate order. For example, for the expression:

$a+b**c+d$

the order of evaluation would be represented as

$((a+(b**c{)}^1{)}^2+d{)}^3$

$($Note$)$ answer this as pervious example using expression precedence written up$)$

a $>$ b xor c or d $17$

$q,$

Question $2$: $($Use your Own Words$).(1\mathrm{.}5$ point$)$

a$.$ What is a loop variable? What is stepsize?

b$.$ Define selection statement.

C$.$ What alternative is provided for goto in Java?
