anofris a is UINT_MAX. It will overflow int. That's the cause of your -1 result. you should be using %u not %d since your variable a is an unsigned int. Because UINT_MAX > INT_MAX, int wraps back to negative values if you exceed the signed integer max. And a is 1 more than twice of INT_MAX. https://sololearn.com/compiler-playground/cmxS5FT5ItNc/?ref=app
