Answer 1

Answer:

Note: To run program your Story.txt file need to be in same folder where program file is stored.

Code:

#include<iostream>
#include<fstream>
using namespace std;
int main()
{
string str;
ifstream infile{"Story.txt"}; //creating input file stream object
ofstream outfile{"DuplicateStory.txt"};//creating output file stream object
   if(infile && outfile)// validate both files
   {
while(getline(infile,str))//read line from input file upto the end
       {
outfile << str << "\n";//writing line 1st time
           outfile << str << "\n";//writing line 2nd time
           outfile << str << "\n";//writing line 3rd time
}
cout << "File copied successfully \n";
} else //if error with any file
   {
printf("Cannot read File");
}
infile.close();//Closing file Story.txt
outfile.close();//Closing file DuplicateStory.txt
return 0;
}
