The answer
If you have 4 or 5 boolean flags tracking complex state, the code becomes hard to read. It's usually better to refactor into a State Machine or separate functions.

Is using multiple flags bad practice?
More FAQs in State Variables and Flags Inside Loops
A boolean flag is a true/false variable used to remember if a specific condition was met during the execution of a loop.
If declared inside the loop block, the variable is created and destroyed on every iteration, meaning it cannot accumulate data or persist after the loop ends.
An accumulator is a variable (usually starting at 0 or an empty string) used to gather and sum up data over multiple iterations of a loop.
