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?

Your going to have to read the input one piece at a time, allocating a bigger buffer as you go. (realloc is the way to go here) I recommend putting the input reading code in a function do you can easily use it multiple times.
