C++中刪除文本的最後一行

讀取文本的每行("\n"), 儲存入數組vector<string>, 輸出時, 少輸出最後一行, 即可.

代碼:

/*  * main.cpp  *  *  Created on: 2014.06.08  *      Author: Spike  */      /*vs 2012*/      #include <windows.h>  #include <fstream>  #include <iostream>  #include <string>  #include <vector>        using namespace std;        int main()  {      vector<string> tmp_files;            ifstream infile( "w.txt" );      if (!infile) {          cout << "fail!" << endl;          return 0;      }            string lineContent;      while ( getline( infile, lineContent, '\n' ) ){          tmp_files.push_back(lineContent + "\n" );      }      infile.close();            ofstream outfile( "w2.txt",ios::out );      vector<string>::iterator siter = tmp_files.begin();            copy( tmp_files.begin(), tmp_files.end()-1, ostream_iterator<string>(outfile) );      cout << "ok!" << endl;      outfile.close();            return 0;  }

輸出:

原始文本(w.txt):  Female  Sister  Girl  Woman  Old Woman        輸出文本(w2.txt):  Female  Sister  Girl  Woman
