我想要做的是输入一个文件LINE BY LINE并标记并输出到输出文件.我能够做的是输入文件中的第一行但我的问题是我无法输入下一行要标记化的行,以便它可以保存为输出文件中的第二行,这是我到目前为止输入文件中的第一行所能做的.

#include <iostream>
#include<string>    //string library
#include<fstream>    //I/O stream input and output library

using namespace std;
const int MAX=300;    //intialization a constant called MAX for line length 
int main()
{
   ifstream in;     //delcraing instream
   ofstream out;    //declaring outstream

   char oneline[MAX];   //declaring character called oneline with a length MAX

   in.open("infile.txt");  //open instream
   out.open("outfile.txt");  //opens outstream
   while(in)
   {

    in.getline(oneline,MAX); //get first line in instream

    char *ptr;      //Declaring a character pointer
    ptr = strtok(oneline," ,");
    //pointer scans first token in line …
