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 forchar name[50]'
