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?

    Hello, ewroiugheqripougheqpiurghperiugheqrpiughqerpuigheq,

    The fgets function will only read in as many characters as you tell it to (50) in the second parameter, so the rest of the input will simply be lost and the name will be truncated.
