CSCI 1301 While, Do-while and For Loop Exercises 1) Given the following loop: int i=19; while (i<29) { i=i+3; } a) What will the value of the variable i be after the loop terminates? b) How many will the body of the loop iterate? c) Rewrite the previous loop as the for loop. 2) Given the following loop: int x=10; while (x >=5 && x<=8) { if (x % 2 == 0) { x=x + 3; } else { x=x -2; } } a) What will the value of the variable x be after the loop terminates? b) How many times will the body of the loop iterate? c) If the initial value of x is 7 instead of 10, how many times will the body of the loop iterate? 3) Given the following loop: int w=1; int count = 0; do { w++; System.out.println("w="+w); } while (w >=5 && w<= 8); a) What will the value of the variable w be after the loop terminates? b) How many times will the body of the loop iterate?4) Given the following loop: int w=0; while (w % 10 != 2) { w= (w + 4) % 2; System.out.println("w="+w); } How many times will the body of the loop iterate? 5) Can you rewrite the following while loop as a do-while loop to produce the same output? int x=0; int sum=0; System.out.println(″Please enter an integer between 0 and 10 :″); x=keyboard.nextInt(); while (x > 0 && x < 10) { sum =+x; System.out.println(″Please enter an integer between 0 and 10 :″); x=keyboard.nextInt(); } 6) Can you rewrite the following do-while loop as a while loop to produce the same output? y = (int) Math.random()*100 + 1; do { System.out.println(″y=″+y); y=2*y + 1; } while (y < 100); 7) What will be produced by the following code fragment? for (int num=10; num <= 100; num++) System.out.println(num); 8) What output will be produced by the following code fragment? int num=1 for (num=10; num <= 100; num++); System.out.println(num); 9) Indicate the output of the following code fragment: for (int num=100; num >= 10; num--){ System.out.println(num); }10) Indicate the output of the following code fragment? int increment=3; for (int num=0; num <= 200; num +=2 + increment*3){ System.out.println(num); } How many times does the previous loop iterate? 11) Indicate the output of the following code fragment? for (int num=1; num <= 42; num +=4){ if (num % 3 == 0) System.out.println(num); } How many times does the previous loop iterate? 12) Indicate the output of the following code fragment? for (int i=30; i > 10; i++) { System.out.println(″i=″+i); } How many times does the previous loop iterate? 12) Given the following code fragment? for (int i=1; i < 15; i+=1) { if (i % 3 == 1) { System.out.println(″i=″+i); continue; } } a) What is the output of the code fragment? b) How many times does the previous for loop iterate? c) Rewrite an equivalent for loop that do not the continue statement.13) Rewrite the following code fragment loop so it does not use any continue and break statements: int i = 100; while (true) { i-=2; if (i % 6 == 0) { System.out.println(i); continue; } if (i % 4 == 0) { System.out.println(i); continue; } if ( i % 7 == 0 && i % 5 == 0) { break; }
