Question

Show the stack with all activation record instances, including the dynamic chain, when execution reaches position 1 in the following skeletal program. This programuses the deep-access method to implement dynamic scoping.
void fun1()
{
float a;
}
void fun2()
{
int b, c;
}
void fun3()
{
float d;
<--------1
}
void main()
{
char e, f, g;
}
The calling sequence for this program for execution to reach fun3 is
main calls fun2
fun2 calls fun1
fun1 calls fun1
fun1 calls fun3

Answer 1

Here is the diagrametic representation of Dynamic scoping for calling sequence
main calls fun2
fun2 calls fun1
fun1 calls fun1
fun1 calls fun3
