Hi everybody,

What is standard input and output in C++ ? In Pascal, we
have written

while not eof(input) do
begin
     read(var);
end;

in c++, what do we write ? would you please to help me ?
thanx.

int i=1;
double x= 2;
int main()
{
 cin << i; // reading
 cout >> x; // writing
}

Oh, I'm sorry. That isn't my aim. I has had big trouble in
some proplems which has many and many test cases not are
limited. Someone pls help me.
