Convert the following for loop segment to an exit-controlled loop.
for (int x = 1, y = 2; x < 11; x += 2, y += 2) {
System.out.println(x + "\t" + y);
}
Answer
int x = 1, y = 2;
do {
System.out.println(x + "\t" + y);
x += 2;
y += 2;
} while (x < 11);
Reason — We need to convert the for loop given in question to a do-while loop as do-while is an exit-controlled loop whereas for and while are entry-controlled loop.
1. Initialization:
- The variables
xandyare initialized before thedo-whileloop:int x = 1, y = 2;.
2. Loop Body:
- The statements inside the
forloop are moved into the body of thedoblock:
System.out.println(x + "\t" + y);
x += 2;
y += 2;
3. Condition Check:
- The condition
x < 11is evaluated after executing the loop body, ensuring the loop is exit-controlled.

(The number is said to be EvenPal number when number is palindrome number (a number is palindrome if it is equal to its reverse) and sum of its digits is an even number.)
