Question: 1 / 400

Which error commonly leads to creating an infinite loop?

Using the wrong data type

Forgetting to update a variable within the loop

An infinite loop occurs when a loop continues to run indefinitely, often because the conditions required to exit the loop are never met. Forgetting to update a variable within the loop is a primary cause of this problem. For example, if a loop is designed to iterate until a variable reaches a certain value, but the code does not include logic to change that variable during each iteration, the condition for stopping the loop will always evaluate as true. This leads to the loop running endlessly because it never meets the criteria for termination.

This type of error highlights the importance of proper loop control and maintaining the state of variables that govern the loop's execution. Ensuring that the loop has a valid exit strategy is crucial for effective programming, as infinite loops can lead to program crashes or unresponsive applications.
