Indicates if the end of a stream has been reached.
bool eof( ) const;
Return Value
true if the end of the stream has been reached, false otherwise.
Remarks
The member function returns true if rdstate & eofbit is nonzero. For more information on eofbit, see ios_base::iostate.
Example
// basic_ios_eof.cpp
// compile with: /EHsc
#include <iostream>
#include <fstream>
using namespace std;
int main( int argc, char* argv[] )
{
fstream fs;
int n = 1;
fs.open( "basic_ios_eof.txt" ); // an empty file
cout << boolalpha
cout << fs.eof() << endl;
fs >> n; // Read the char in the file
cout << fs.eof() << endl;
}
Sample Output
false
true
