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
x
andy
are initialized before thedo-while
loop:int x = 1, y = 2;
.
2. Loop Body:
- The statements inside the
for
loop are moved into the body of thedo
block:
System.out.println(x + "\t" + y);
x += 2;
y += 2;
3. Condition Check:
- The condition
x < 11
is evaluated after executing the loop body, ensuring the loop is exit-controlled.
