Easiest way to convert a string to a vector of letters?

[green abyss]

    std::vector<std::string> ret;
    for (int i=0;i<word.length();i++){
        ret.push_back(word[i]);
    }
}```
The code above gives me an error. I assume the issue arrises because *word[i]* is not a string?

what's the error

oh because word[i] is a char

not std::string, so change the return type to std::vector<char>

You can use a range based for loop for this

for (const char l : word) 
  ret.push_back(l);

or another method using <algorithm> header

// Assuming you allocated enough space in ret already
std::copy(word.begin(), word.end(), ret);

The second version is C++ code

Sounds a bit like an XY problem, maybe just construct a string when you need it like std::string(1, word[n]);

[sweet wolf]

std::vector<char> to_vector(const std::string& word){
   return std::vector<char>(word.begin(), word.end());
}

there is no good reason for you to need a vector of strings, each element of a string is a char, so you get a vector of char

if you really want them, then do the conversions manually

std::vector<std::string> to_vector(const std::string& word){
    std::vector<std::string> ret;
    ret.reserve(word.size());
    for (int i=0;i<word.length();i++){
        ret.push_back(std::string(word[i]));
    }
    return ret
}
