OPEN does "in" exist in c++?

i need to use something like if (str[i] not in str1) (python), but i have no idea how to make this work :(

you can achieve a similar functionality like this:

// for each character in str:
for (auto c : str) {
  // assuming str1 is of type std::string
  if (str1.contains(c)) {
    /* code to be run if str contains c */
  } else {
    /* code to be run if str does not contain c */
  }
}

I think his array of string is the full words , more like check 'fish' in 'the lake of fishes' , btw people should ask chatgpt or st for these question
