Chapter 5.6, Problem 5.6.2CP
What are the differences between a while loop and a do-while loop? Convert the following while loop into a do-while loop:
Scanner input= new Scanner(System.in);
int sum = 0;
System.out.println("Enter an integer " +
"(the input ends if it is 0)");
int number = input.nextInt();
while (number != 0) {
sum += number;
System.out.println("Enter an integer " +
"(the input ends if it is 0)");
number = input.nextlnt();
}

The following do...while loop rewritten as a for loop would be:
int num = 5;
do {
System.out.print(num + " " );
num *= 3; //num = num * 3;
} while (num <= 30);
All of these are correct.
int num = 5;
for (num <= 30) {
System.out.print(num + " ");
num *= 3;
}
for (int num = 5; num <= 30) {
System.out.print(num + " ");
num *= 3;
}
for (int num = 5; num <= 30; num *= 3) {
System.out.print(num + " " );
}
Convert the following for loop definition to a do while loop: for(int j= 100; j > 0; j--) {
if (j % 2 != 0) System.out.println (val); }
12.
In .............., the bodies of the two loops are merged together to form a single loop provided that they do not make any references to each other.
a.
Loop unrolling
b.
Strength reduction
c.
Loop concatenation
d.
