[Error] no matching function for call to 'std::basic_ofstream<char>::basic_ofstream(std::string&)'

This error occurs when the std::ofstream constructor is given a string argument instead of a character array (const char*) argument. To fix this error, you can pass the string argument as a c_str() of the string, like this:

std::string filename = "example.txt";
std::ofstream outfile(filename.c_str());

Alternatively, you can use the constructor that takes a std::string_view argument, which was introduced in C++17:

std::string filename = "example.txt";
std::ofstream outfile(std::string_view(filename));
