    I forgot to assign a variable, now it crashes %5 of the time. It’s wild how c doesn’t default variables to null or something.

      default variables to null or something

      That is such a bad idea. Better to have the compiler warn you about it like in Rust, or have the linter / IDE highlight it.

        If it’s going to compile without any warnings I’d rather the app crash rather than continue execution with rogue values as it does now.

        There is so much room for things like corrupted files or undocumented behavior until it crashes. Without the compiler babysitting you it’s a lot easier to find broken variables when they don’t point to garbage.

          Just enable all compiler warnings (and disable the ones you don’t care about), a good C compiler can tell you about using unassigned variables.

            Still learning, they just covered compiler flags in cs. They didn’t go into detail yet though.

            Edit: I’ve used python for years and they have something equally dumb. You can have a function in a massive application that is broken and the moment it’s called, the application crashes.

            At any other point the application will just run as if nothing is wrong even though python evaluates everything at runtime. I’m sure they can’t do much because the initial launch would be slow.

      C does exactly what you tell it, no more. Why waste cycles setting a variable to a zero state when a correct program will set it to whatever initial state it expects? It is not user friendly, but it is performant.

        It wouldn’t be that much processing compared to the rest of the app. It would lot more efficient than running an effectively infinite loop or arithmetic on an arbitrarily large number as a result of an unsigned variables.
