c++ - Issues when reading from a .cpp file -

i have file call text.cpp. mission read file.

text.cpp file (inside file)

#include <iostream>      #include <cstring> #include <ctype.h> #include "program.h" #include "binarytree.h"  #include "linkedlist.h" 

when detect

 '#' symbol 

the system start looping, if detect '<' & '"' symbol, print out remain word. example output : iostraem

i can detect '<' symbol , print output success. when detect '"' symbol, can print remain word (program.h), follow 烫烫烫烫烫烫烫烫烫烫烫烫烫烫烫 behind word.

may know whats wrong of code?

my code below:

 #include <iostream>     #include <string>     #include <fstream>      using namespace std;      int main()      {   char template[100];         char filename[20];       cout << "enter filename:" ;     cin >> filename;      fstream read(filename);     if (read.is_open())     {         while(!read.eof())         {         read.getline(template, 100);              (int k = 0; k < 100 ;k++)             {                 if(template[k] == '#')                 {                     for(int = 0; < 100; i++)                     {                         if(template[i] == '<' ||  template[i] == '"')                         {                             (int j = i+1; j < 100; j++)                             {                                 if(template[j] == '>' || template[j] == '"')                                 {                                     break;                                  }                                 cout << template[j];                              }                             cout  <<endl;                         }                            }                  }             }         }     }      else     {         cout << "file not exist, press enter exit program." <<  endl;         system("pause");         exit(exit_success);      }     system("pause");  } 

output:

enter filename: text.cpp iostream cstring ctype.h program.h  ype.h binarytree.h  烫烫烫烫烫烫烫烫烫烫烫烫烫烫烫 linkedlist.h  烫烫烫烫烫烫烫烫烫烫烫烫烫烫烫烫烫烫烫烫 

this way more complicated needs be. might consider this:

#include <iostream> #include <string> #include <fstream>  int main() {        std::string inputfilename;     std::cout << "enter filename:";     std::cin >> inputfilename;      std::ifstream inputfile(inputfilename);     if(inputfile)     {         std::string line;         while(std::getline(inputfile, line))         {             if(line.find('#') != std::string::npos)             {                 size_t startpos = line.find_first_of("<\"");                 size_t endpos = line.find_last_of(">\"");                 if(startpos != std::string::npos && endpos != std::string::npos)                 {                     //advance start after < or "                     ++startpos;                     //sanity check in case line ill formed                     if(startpos < endpos)                     {                         std::cout << line.substr(startpos, endpos - startpos) << std::endl;                     }                 }             }         }     }     else     {         std::cout << "file '" << inputfilename << "' not exist." <<  std::endl;     }     return 0; }
