let’s say I have this code

` #include #include char name[50]; int main(){ fgets(name,50,stdin); name[strcspn(name, “\n”)] = ‘\0’; printf(“hi %s”, name); }

` and I decide my name is “ewroiugheqripougheqpiurghperiugheqrpiughqerpuigheqrpiugherpiugheqrpiughqerpioghqe4r”, my program will throw some unexpected behavior. How would I mitigate this?

    Why is this even still in the library 🥲

    Twenty years ago it kind of made sense. Ok it’s bad, but sometimes we’re just reading a local file fully under our control, maybe from old code that the source doesn’t exist anymore for, it’s such a core function that taking it out however badly needed will have some negative consequences.

    At this point though, I feel like calling it should just play a loud, stern “NO!” over your speakers and exit the program.

      The linker will complain at you —
