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?

Can’t help with your code, but you should be aware of:

The first article is funny, because I moved from my native country to the one right next to it, and everybody is confused by my name. They have one given name and 2 family names, while I have 4 first names, and a compound last name.

No need to travel to the other side of the planet to meet a different culture of naming.

Not a name, but something else to be aware of which could also happen with names.

Wow. Almost worth changing my name again just to fuck with them.
