C++程式中擷取不帶檔案路徑和尾碼的檔案名稱

string getName(const char* full_name){string file_name = full_name;const char*  mn_first = full_name;const char*  mn_last  = full_name + strlen( full_name );if ( strrchr( full_name, '\\' ) != NULL )mn_first = strrchr( full_name, '\\' ) + 1;else if ( strrchr( full_name, '/' ) != NULL )mn_first = strrchr( full_name, '/' ) + 1;if ( strrchr( full_name, '.' ) != NULL )mn_last = strrchr( full_name, '.' );if ( mn_last < mn_first )mn_last = full_name + strlen( full_name );file_name.assign( mn_first, mn_last );return file_name;}

擷取尾碼名（不包含.）

string getExt(string full_name){return full_name.rfind(".") == string.npos ? full_name : full_name.substr(full_name.rfind(".")+1);}
