1. Show the stack with all activation record instances, including static and dynamic chains, when execution reaches position 1 in the following skeletal program.  

procedure MAIN 
   var x: integer;
   var z: integer;
   procedure fun1 (x: integer);
      procedure fun2 (x: integer);
         var y: integer
         begin 
           y := z + x;
           fun1(y);
         end;  
      begin  
        print(x);   <------------ 1
      end;
   procedure fun3(x: integer)
      var y: integer;
      var z: integer;
      begin
          z:=1; 
          y:= x + 2;
          fun2(y);
      end;  
   begin  
     x:= 5;
     z:= 3;
     fun3(x);
   end;  
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

2. Show the stack with all activation record instances, incliding static and dynamic
chains, when execution reaches position 1 in the following skeletal program.

int x=8, y=4, z=1;
void main()
{
   int z=5;
   fun1(z);
}

void fun1(int m)
{
    int z=2;
    y = y + m;
    fun2(y);
}

void fun2(int n)
{
   z = z - n;
   cout<<z<<endl;   <------------ 1
}
