从行字符串

您好，

我想逐行读取文件中的一行，并从每一行是由space.I分离得到的字符串，我做这样的事情:

ifstream fin;

string dir, filepath;

DIR *dp;

 cout << "dir to get files of: ";

  getline( cin, dir );  // gets everything the user ENTERs



  dp = opendir( dir.c_str() );

  if (dp == NULL)

    {

    cout << "Error(" << errno << ") opening " << dir << endl;

    return errno;

    }

 

  while ((dirp = readdir( dp )))

    {

	 filepath = dir + "/" + dirp->d_name;

    string str="h";

    fin.open( filepath.c_str() );

 

   pos=filepath.find(".");

    //Way to turn a string into const char* using c_str()

   const char* str1=(filepath.substr(pos+1)).c_str();

   //compare the strings

   if((filepath.substr(pos+1).compare(str))==0)

   {

	   char character;

	   cout<<"FoundC"<<endl;

	   cout<<filepath<<": "<<num<<endl;

	   std::string line;

	   std::string word;

	   std::getline(fin,line);

	   cout<<"getline"<<": "<<"line"<<endl;

	   if(fin.get(character).good())

	   {

		   while(character!='\n')

			   word = GetStringsFromLine(line);

 

	   }

	   cout << line << endl;

	   cout << word << endl;

	   cout << buffer <<endl;

   }

 

std::string& GetStringsFromLine(std::string& line)

{

 std::string str2;

 

 int position=0;

 std::stringstream ss;

 cout << "line=" << line << endl;

 

  		 while( (line.at(position) != (isspace(line.at(position)))) )

  		 {

  			 ss<<line.at(position);

  			 ss>>str2;

  			 position++;

  			 cout << "position=" << position << endl;

  		 }

  		 	 cout << "str2=" << str2 << endl;

 return str2;

}
