i was making a program that reads a text file(2of12.txt) word by word, searches it in second one(all_dict.txt)..if not found it pastes it into second one....the problem is that it only pastes 1st letter of each word plz help.

Code: Select all

void main()
{   ifstream myReadFile,x2;
   ofstream myWriteFile;
   char output[100],s[100];
   myReadFile.open("2of12.txt");
   x2.open("all_dict.txt");
   
   int i,flag;
   for( i = 0; i<100; i++, output[i] = '\0',s[i]= '\0');
   
   if (myReadFile.is_open() && x2.is_open())
   {   
      while(!myReadFile.eof())
      {   
         flag = 0;
         myReadFile >> output;
         while(!x2.eof())
         {   for( i = 0; i<100; i++, output[i] = '\0',s[i]= '\0');
            x2>>s;
            if(strcmp(s,output)==0) flag = 1;
         }
         x2.seekg(0,ios::beg); //reset read pos to beginning
         x2.clear(); //clear eofbit
         
         if(flag==0)
         {
            
            myWriteFile.open ("all_dict.txt",ios_base::app);
            myWriteFile<<output<<endl;
            myWriteFile.close();
            myWriteFile.clear(); //clear eofbit
         
         }
            
      }
   }

   myReadFile.seekg(0,std::ios::beg); //reset read pos to beginning
   myReadFile.clear(); //clear eofbit
   myReadFile.close();

   


}

also after some time i get this error

Your for loop is erasing all but the first character in output
I'm assuming you're using it to clear the buffers, which is not achieved
you should use memset or some c++ equivalent instead.
