C读取文件

C读取文件，这种写法不会多一行。

 #include "stdafx.h"
 #include <vector>
 using namespace std;
 struct PointXYZ
 {
     double X;
     double Y;
     double Z;
 };

 int _tmain(int argc, _TCHAR* argv[])
 {
      FILE* in=fopen("D:\\project60-cut-1000.txt","r");
      if(in==NULL)
      {
          printf("missing file");
          return ;
      }
      double tmp=;
      //char buff[255] = {};
      float x;
      float y;
      float z;
      vector<PointXYZ> *points=new vector<PointXYZ>();
      char* str;
      int i=;
     // while(!feof(in))
      fscanf(in,"%f %f %f",&x,&y,&z);
      while(feof(in)==) /*判断是否文件尾，不是则循环*/
      {
          i++;
          PointXYZ point;
          point.X=x;
          point.Y=y;
          point.Z=z;
          points->push_back(point);
          fscanf(in,"%f %f %f",&x,&y,&z);
      }
      fclose(in);

      for (vector<PointXYZ>::iterator iter = points->begin(); iter != points->end(); ++iter)
      {
          PointXYZ tmp=(PointXYZ)*iter;
          printf("%f %f %f\n",tmp.X,tmp.Y,tmp.Z);
      }
      printf("Number：%d\n",(int)points->size());
       system("pause");//getchar();
      return ;
 }

参考C++的读取

 void LoadImages(const string &strAssociationFilename, vector<string> &vstrImageFilenamesRGB,
                 vector<string> &vstrImageFilenamesD, vector<double> &vTimestamps)
 {
     ifstream fAssociation;
     fAssociation.open(strAssociationFilename.c_str());
     while(!fAssociation.eof())
     {
         string s;
         getline(fAssociation,s);
         if(!s.empty())
         {
             stringstream ss;
             ss << s;
             double t;
             string sRGB, sD;
             ss >> t;
             vTimestamps.push_back(t);
             ss >> sRGB;
             vstrImageFilenamesRGB.push_back(sRGB);
             ss >> t;
             ss >> sD;
             vstrImageFilenamesD.push_back(sD);

         }
     }
 }
