Chapter 5 Loops 1. How many times will the following code print "Welcome to Java"? int count =0; while (count >=0){ System.out.printin(" Welcome to Java"); \} a. 8 b. 9 c. 10 d. 11 e. infinity 2. What is the output of the following code? int x=0; while (x0){ number =3; System.out.print(number +m ); \} a. 630 b. 63 c. 30 d. 303 e. 0-3 4. What will be the output of the code below when executed"? long num =12356; long result=0; while (num>0)\{ result=result* 10+ num %10; num/=10; System.out.println(result); a. 0 b. 100 c. 123 d. 654321 e. 356 5. What is the value in count after the following loop is executed? int count = 0; do \{ Syste while (coun System.out.p a.b.c.d.e.8910110 System.out.printin("Welcome to Java"); \} while (count++d=0;d10 would always be true. d. The program compiles and runs fine. 8. Which of the following loops correctly computes 1/2+2/3+3/4++99/100 ? A: double sum =0; for (int i=1;i=1;j) System.out.print (j=1;j ) System.out.print (j>=i?j+m=m+n+m ? ; System.out.println(); 19. To add 0.01+0.02++1.00, what order should you use to add the numbers to get better accuracy? a. add 0.01,0.02,,1.00 in this order to a sum variable whose initial value is 0 . b. add 1.00,0.99,0.98,,0.02,0.01 in this order to a sum variable whose initial value is 0 . 20. Analyze the following code, what option describe the cod? double sum = 0 ; for (double d=0;d 4) break; \} while (item =4 ) continue; sum += item; while (item =1 ) \{ if (balance =1 ) \{ if (balance
