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?

      Aside from the obvious effect of truncating long names, this could be dangerous if the 50-byte boundary is in the middle of a Unicode codepoint.

      name[50] is out of bounds for char name[50]'
