Please how can I read to and from a file on this platform? ( using “fstream” in C++)

Answer 1

I can't understand what you mean... Please be more clear.

Answer 2

In order to add a new file, you can use the shortcut Ctrl-M.

If you mean how to use fstream, then you have to:

#include <fstream>

//after using namespace std; you have to put the next lines:

ifstream f("file.in");

ofstream g("file.out");///the name "file can be changed to whatever name you want, as long as you create files with the same names

//now you can use f exactly like you would use cin and g like cout

//note that instead of f you can put fin or whatever you like;

//the same goes for g
