How can I convert const char* to string and then back to char*?

A: The std::string class has a constructor that takes a char const*, so you simply create an instance to do your conversion.

B: Instances of std::string have a c_str() member function that returns a char const* that you can use to convert back to char const*.

auto my_cstr = "Hello";        // A
std::string s(my_cstr);        // A
// ... modify 's' ...
auto back_to_cstr = s.c_str(); // B
