I'm trying to make a terminal hacking game the same as fallout, but I'm struggling to get the number of characters matching between the user input and the correct password. I've tried searching but so far I haven't found any simple solutions. Please can someone suggest a way? I've also included the full class code below for any tips on improving it

case difficulty::hard: lower = 8; upper = 12; break;
}
int a = rand_eng(lower, upper);
fill_vec(a);
this->fill_addresses(a);
this->fill_characters();
int vec_size = passwds.size();
int b = rand_eng(0, vec_size-1);
answer = passwds[b];
return;
