stream similar to cout and cin in <iosteam> library but is <fstream> for file stream.
ifstream in_stream creates an input stream object, in_stream, that can be used to input text from a file to C++.
ofstream out_stream creates an output stream object,out_steam, that can be used to write text from C++ to a file.
.eof() is a method for the instance variables of fstream, input and output stream objects, and can be used to carry out a task until a file has ended or do some task after a file has ended.
inputn when the following code runs.
#include <fstream>
#include <cstdlib>
#include <iostream>
using namespace std;
main(){
ifstream in_stream;
ofstream out_stream;
int inputn;
out_stream.open("anotherFile.txt");
out_stream << 25;
out_stream << 15 << endl;
out_stream << 101 << endl;
in_stream.open("anotherFile.txt");
in_stream >> inputn;
cout << inputn;
in_stream >> inputn;
}
