What happens if the termination condition in a for loop evaluates to false?
Understand the Problem
The question is asking about the behavior of a for loop when its termination condition is evaluated as false. It is seeking to clarify what the consequences are under this circumstance.
Answer
The loop terminates.
If the termination condition in a for loop evaluates to false, the loop terminates immediately, and the block of code inside the loop is not executed.
Answer for screen readers
If the termination condition in a for loop evaluates to false, the loop terminates immediately, and the block of code inside the loop is not executed.
More Information
For loops frequently check a termination condition before each iteration. If the condition evaluates to false at the beginning, the loop will not execute even once. In programming, this helps avoid unnecessary execution of code blocks and can prevent potential errors or infinite loops.
Tips
A common mistake is assuming the loop body will execute at least once. In a for loop, the termination condition is evaluated before the body executes, unlike a do-while loop where it is checked afterward.
