c_str
Syntax: 
  #include <string>
  const char* c_str();

The function c_str() returns a const pointer to a regular C string, identical to the current string. The returned string is null-terminated.

Note that since the returned pointer is of type const, the character data that c_str() returns cannot be modified. Furthermore, you do not need to call free() or delete on this pointer.
