Read line from .txt, store in char*

This! Is! C++!
Is this impossible?
I'm only able to store stuff in strings. But strings cannot be converted to char*, only const char*. And const char* can't be used in place of char*.

Can't I just do something like getline(char* text,256,' ')? Or will have I have to copy data from a string into a char*?

// assuming s is the String
char* char_s = new char[(s.length()+1)];
// char* char_s = (char*)malloc( sizeof(char)*(s.length()+1) );
strcpy(char_s, s.c_str());
