PT.O
3 a) Discuss the following method for transmitting parameter with the help of examples *
(i) Call-by-name
(ii) Call-hy-value result. OS
b) Prolog rules can be viewed as logical predicates. The rule a:- b, c will cause a to succeed if b and c both succeed. So we can say a is true if b A c is true.

{ constz= 10,
# define maxval = 20, intk; char A [5], k = max val; if (N > Z)
return (2*z + k);
b) Discuss the advantages and disadvantages of dynamic type checking over static type checking. OS
c) Write an iterative function in LISP named sum-all ( ) using do that takes an integer n as argument and returns sum of integers from 1 to n. For example
