ios eof() function in C++ with Examples

The eof() method of ios class in C++ is used to check if the stream is has raised any EOF (End Of File) error. It means that this function will check if this stream has its eofbit set.

Syntax:

bool eof() const;

Parameters: This method does not accept any parameter.

Return Value: This method returns true if the stream has eofbit set, else false.

Example 1:

// C++ code to demonstrate 
// the working of eof() function 
  
#include <bits/stdc++.h> 
using namespace std; 
  
int main() 
{ 
  
    // Stream 
    stringstream ss; 
  
    // Using eof() function 
    bool isEOF = ss.eof(); 
  
    // print result 
    cout << "is stream eof: "
         << isEOF << endl; 
  
    return 0; 
} 

Output:

is stream eof: 0

Example 2:

// C++ code to demonstrate 
// the working of eof() function 
  
#include <bits/stdc++.h> 
using namespace std; 
  
int main() 
{ 
  
    // Stream 
    stringstream ss; 
    ss.clear(ss.eofbit); 
  
    // Using eof() function 
    bool isEOF = ss.eof(); 
  
    // print result 
    cout << "is stream eof: "
         << isEOF << endl; 
  
    return 0; 
} 

Output:

is stream eof: 1
