I have a string which contains ` char and I want to replace it with escaped form of same char.

// Turns ` to \' 
std::replace(script.begin(), script.end(), std::string("\\`"), std::string("\\\\`"));

However, the code won't compile,

error: invalid operands to binary expression ('char' and 'const std::basic_string<char>')
        if (*__first == __old_value)
            ~~~~~~~~ ^  ~~~~~~~~~~~
note: in instantiation of function template specialization
      'std::replace<std::__wrap_iter<char *>, std::basic_string<char>>' requested here
            std::replace(script.begin(), script.end(), std::string("\\`"), std::string("\\\\`"));

std::replace replaces a single element of a sequence with a single element, not arbitrary subsequences. You probably want std::regex_replace. – n. m. could be an AI Sep 23 '21 at 21:46
@n.1.8e9-where's-my-sharem. This replace single element. You didn't read my question and closed it. WTF! – jeffbRTC Sep 23 '21 at 22:16
@n.1.8e9-where's-my-sharem. I posted this question to solve the types issue!!! – jeffbRTC Sep 23 '21 at 22:19
I didn't close it, someone else did. Make sure you read all the answers to the duplicate question. – n. m. could be an AI Sep 24 '21 at 06:24
