Problem 1. Consider the following type declarations
ΤΥΡE
A1 : integer;
A2 : pointer to float;
A3 : pointer to integer;
T1 : structure { x : integer; }
T2 : structure { x : A;
next : pointer to integer; }
T3 : structure { a
: integer;
b: float; }
T4 :
structure { b: float;
: integer; }
a
T5 : structure { a
: pointer to T5; b : pointer to T6; c
: pointer to T7; }
T6 : structure { a
: pointer to T6; b : pointer to T5; c : pointer to T5; }
T7 : structure { a
: pointer to T6; b : pointer to T7; c : pointer to T9; }
T8 :
structure { a
: pointer to T7; b : pointer to T 6; c : pointer to T10; }
T9 : array [4] [5] of T8;
T10 : array [4] [5] of T7;
// array 4 rows 5 columns
Assuming the most permissive definition of structural equivalence, which types are
structurally equivalent?
