1. Let the function fun be defined as (10 pts)

fun(int *k)

{

*k +=4;

return 3 * (*k) - 1; }

suppose fun is used in the program as follows

void main( ){

int i = 10, j = 10, sum1, sum2;

sum1 = (i / 2) + fun ( &i );

sum2 = fun ( &j ) + ( j / 2);}

What are the values of sum1 and sum2

a. Operands in the expressions are evaluated left to right?

b. Operands in the expressions are evaluated right to left?

2.Consider the following JavaScript Skeletal program (10 pts)

// the main program

var x;

function sub1( ) {

var x;

function sub2( ) {

}

}

function sub3 ( ) {

..

}

Assume that the execution of this program is in the following unit order:

main calls sub1

sub1 calls sub2

sub2 calls sub3

a. Assuming static scoping, in the following, which declaration of x is the correct one for reference to x

i)sub1 ii) sub2 ii) sub 3

b.Repeat part a but assume dynamic scoping.

3. Write a Scheme function get-odd-nums that accepts a list of numbers and returns a new list that contains only the odd numbers. (5 pts)

Example: (get-odd-nums ' (1 2 3 4 5 6 7 8 9 )) should return (9 7 5 3 1)
