删除文本的最后一行 代码(C++)

读取文本的每行("\n"), 存储入数组vector<string>, 输出时, 少输出最后一行, 即可.

代码:

/* * 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;}

输出:

原始文本(w.txt):FemaleSisterGirlWomanOld Woman输出文本(w2.txt):FemaleSisterGirlWoman
