37. Insert the following C code fragment in main() of Figure 6.48 just before the return statement:

sum = 0; p = first;

while (p != 0) {

sum += p->data;

p = p->next;

}

printf("Sum: %d", sum);

and translate the complete program to Pep/9 assembly language. Declare sum to be a local variable along with the other locals as follows:

struct node *first, *p;

int value, sum;
