POL208Y1 : Compilation of 1 Semester. Important info.

12. What will the following print ? public class Test public static void main (String[] args) boolean bl = true; boolean b2 = false; boolean b3 = true; if ((bl && b2) || (b2 && b3) || b2) System.out.print("ok"); if ((bl && b2) || (b2 && b3) 11 (bl || b2)) System.out.println("dokey"); (A) No output is produced (B) ok (C) dokey (D) Compile-time error (E) ok dokey

57. Line 5 (A) for (int j = -i*2; j<= i*2; j++){ (B) for (int j = 0; j< i+2+1; j++){ (C) for (int j = -i; j> i; j++) { (D) for (int j = 0; j<= i*2; j++){ (E) for (int j = i; j<= i+2; j+i) {

7. 16 marks Complete the Scheme function within which consumes a number n, a non-negative number base, and a non-negative number range, and produces crue il n satisfies (base - range) < n <= (base + range), and fa-se if not. For example, (within 10 5 6) => true, and within 10 5 2) => false. (define (within n base rarge)
