If (-1) {}

Question

What happens if the value of my if-statement becomes -1 ? Is it the same for all languages?

Answer 1

Okay, that should be fine. More generally, any nonzero integer is treated as true.

Answer 2

For all the languages I know of, -1 is considered as true. So the if block will be executed.

Answer 3

good to know, I wanted to reuse a function that returned -1 in the case of an error 😅
