如何操作std::string和const char*

atfa

[code:1]      std::cin >> usermsg;
      if ( strcmp(usermsg,"quit"))
           return 0;[/code:1]

编译时报错：[code:1]error: cannot convert ‘std::string’ to ‘const char*’ for argument ‘1’ to ‘int strcmp(const char*, const char*)’[/code:1]

请教了

[code:1]if ( strcmp( usermsg.c_str(), "quit") )[/code:1]
或者
[code:1]if ( strcmp( usermsg == "quit" ) )[/code:1]

The former one is preferred.
