Question

I need help editing this program using theeof()

#include<iostream>

#include<fstream>// for files

using namespace std;

int main()

{

ofstream file_out("test.txt", ios::app);//creates the file

for(int i=1; i<=20; i++)//displays the integers code

{

file_out << i << endl;//closes the file

}

file_out.close();

ifstream file_in("test.txt");

int i;

while(file_in >> i)

{

cout << i << " ";//displays file onto the command prompt

}

file_in.close();//closes file

return 0;//ends program

}

Explanation / Answer

its simple when you are using ifstream to read the data instead of while(file_in>>i) you can use while(!file_in.eof()) this means that till the eof is not reached it will continue the loop... and then inside the while loop read the file using file_in >> i .. done . ... cheers!!
