The correct answer is A. Loop exit condition.
A loop exit condition is a condition that is checked at the end of each iteration of a loop. If the condition is true, the loop terminates. If the condition is false, the loop continues.
A loop is a control flow statement that allows a program to repeat a block of code multiple times. The most common type of loop is the while loop. A while loop repeats a block of code as long as a condition is true.
The syntax for a while loop is as follows:
while (condition) {
// code to be executed
}
The condition is evaluated at the beginning of each iteration of the loop. If the condition is true, the code inside the loop is executed. If the condition is false, the loop terminates.
For example, the following code prints the numbers from 1 to 10:
int i = 1;
while (i <= 10) {
System.out.println(i);
i++;
}
The loop exit condition is i <= 10. This condition is evaluated at the beginning of each iteration of the loop. As long as i is less than or equal to 10, the code inside the loop is executed. When i becomes 11, the condition is false and the loop terminates.
The other options are incorrect because they do not describe the requirement for not repeating the instructions.
- Option B, Looping condition, is the condition that is checked at the beginning of each iteration of a loop. If the condition is true, the loop body is executed. If the condition is false, the loop terminates.
- Option C, Conditional statement, is a statement that is executed only if a certain condition is true.
- Option D, Iterative statement, is a statement that is executed repeatedly until a certain condition is met.
