Why can't you use C standard library?

Variant 1. Use std::string::c_str() function to convert a std::string to a C-string (char *)

Variant 2. Use std::string::find(char, size_t) to find a necessary symbol ('\t' in your case) than make a new string with std::string::substr. Loop saving a 'current position' till the end of line.
